Unable to activate Muse Sounds

I have a problem with Muse Sounds for Linux. I've just started a MuseScore Pro+ subscription and hit this problem right away, Ive now spent hours and days trying to find a solution on MuseScore and the communities and all I have gained is a headache, because after looking into the problem I'm about to raise a discussion for, I happened to run the UI check for the Muse Sampler and it returns the error "Muse Sampler Library not found!" and on checking the logs where there are lots of errors, perhaps mostly not significant and not show stoppers, but an error in the log confirms MuseScore cannot find its own library, specifically the Muse Sampler (LibMuseSamplerCoreLib.so).

I spent most of my career in the software engineering lifecycle where I spent most of the time analysing and solving software problems and in also in quality assurance ensuring that the GUI interface of all software products and underlying functions worked as per the specifications and were as logical, simple and straightforward and intuitive as possible and in the case of MuseScore that seems to be generally the case and its an amazing feat of software engineering since it makes what is an incredibly complex subject relatively easy and intuitive and I've found I can use most features with ease and MuseScore is evidently a soundly engineered and well rounded product, except for this issue, which at first glance looks like it would be a pretty simple and straightforward task, but the problem I have encountered is that after having selected the playback setup for a score, there are 2 options for what MuseScore calls Sound Fonts, the first option is MS Basic which is the default option as expected and thats all fine, then there is the Muse Sounds which is an absolute must add-on for me, but which out of the box is unavailable and ghosted out and the end user cannot simply enable/activate this from the UI themselves and after research I found that MuseScore4 doesnt have a built-in feature to perform this function, but instead the onus is placed on the end user to download a separate application, namely Muse Sounds Manager (Linux) Muse Hub elsewhere and all it does is downloads the additional Muse Sounds the user chooses and saves them to a default location, which I found after running tests, takes way longer than necessary to download compared to all other downloads on my system of the same size and it seems that MuseScore4 and Muse Sounds are unaware of each others existence, because in practise, MuseScore4 appears to be unaware that Muse Sounds Manager is installed and whether it has any Muse Sound packages downloaded and available and likewise Muse Sounds is seemingly unware of whether MuseScore is installed or if it is, its certainly not aware of the location where MuseScore stores the additional Muse Sound Fonts, because if it did MuseScore would then enable the Muse Sounds options and make the sounds available wherever applicable in the UI, but it doesnt and so far Ive spent hours and days trying to find a solution and Ive seen the same issues raised several times on the previous version, for example see:

https://github.com/musescore/MuseScore/issues/15670

Which I appear to have precisely reproduced in MuseScore4.

Any assistance would be much appreciated.

In my humble opinion, having a separate Sounds Manager is overkill and all it appears to do is to add unecessary complexity to what should be a quick and simple task, when by far the most simple, logical and intuitive way of activating the Muse Sounds feature, would be to simply provide Muse Sounds in the form of a plugin, because the way the plugin feature works in MuseScore is so simple its a breeze andit seems odd that Muse Sounds is not simply a plugin.
