how to write a pinch harmonics on guitar in musescore

I am a bit unsure what was missed but I'll try to detail it fully. (I also made a video without commentary where I go through the whole process. My musescore isn't in english but nothing should have been moved)
-Put the note in the score.
-Look to the top of your screen. Mine is in a different language but normally you should have from right to left something like "Files; Edits; Appearance; Add; etc.". Left click on add.
-A menu with 7 options should appear. Left click on the 6th one called "Text".
-Another menu now appears including multiple text options separated into 3 groups by lines. Left click the second option in the second group. It should be called "Staff text" and have the shortcut "Ctrl+T" written to the right of it.
-Now you may write "Pinched harmonic" or whatever you want the musician to see on the score and you should see it be written above the note you put earlier (it is necessary that text is written in this step. If you don't need the musician to see anything, you can go into the Appearance menu later and hide the text)
-Once it is done, left click wherever to indicate the program you have finished to write your text.
-Here is where I think your issue happened. Right click the text you wrote.
-A menu called "Staff text" should appear with options separated into 4 groups by lines. In the second group, left click the second option called "Staff text properties" (if it isn't there, maybe check if you are on a recent enough version of musescore?)
-Now appears the staff text properties menu which should be on the "channel changes" submenu which has 4 lines with each containing a box for all the 4 voices and a drop down menu for the canal normally displaying "open".
-Choose a line (doesn't matter which) and left click on the voice of the note you want to use pinched harmonics for.
-On the same line, left click on the dropdown menu. 5 options should appear, the first of which is "harmonics". Left click it.
-Click OK on the bottom right of the menu

And now the note should be played with pinched harmonics. Note that the instrument will be playing pinched harmonics for every note from this point until you add another staff text to tell it to play using the "open" canal again.
If this more detailed version still doesn't work, feel free to message me again but please be as precise as possible so I don't have any doubts as to what the issue is.
