Hiding instrument but keeping playback

OS: Windows 10 Version 2009 or later, Arch.: x86_64, MuseScore Studio version (64-bit): 4.3.0-241231433, revision: 5f36e74

I am wishing to hide a drum(kit) part I have written but still hear its playback.
The handbook says:

"Hiding a staff but keeping its playback
1.(Mandatory) Click on a staff label (E.g. "Treble clef"), but not its instrument."

I take that to mean that I click on the 2 slash lines that represent the drum clef. Then:

"2.Click its Eye icon."

That successfully hides the drum kit but also silences the playback.

Could someone please enlighten me as to which bit of the explanation I have obviously completely misunderstood? Thank you.
