In MuseScore, how can I make small note size cues in specific parts that are invisible in full score?

In MuseScore 4, how can I make small note size cues in specific parts that are invisible in full score?

For example, whenever any instrument has many measures of rests, I'd like to add a few measures of cue notes prior to that instrument's next entrance. I do NOT want these to appear in the full score.

This seems to have been straightforward in MuseScore 3, but I can't, so far, find any guide for this in MuseScore 4.

Thanks, in advance for your help!
