Delay audio + 1 video track without affecting other video track

I'm using Camtasia 2019 to create a technical training video. I have first recorded slides and audio (in one pass) using the PPT plugin. These are in tracks 2 and 3. Track 1 is for demo sections that I recorded and imported seperately (during demos the slides remain visible, zoomed into a small PIP area in the corner; that's why I have the tracks in this order).
I have two more tracks that I use for visual effects and callouts et, in tracks 4 and 5, but I don't think they are relevant for this question.

During editing I noticed that my audio + powerpoint recording went too fast for a specific demo, so I try to edit tracks 2 and 3 to add three extra seconds of silence while the demo plays out.

My first idea, extend frame, failed. Extend frame apparently doesn't affect audio. It would align the powerpoint with the demos, but the audio would then be out of sync with both demos and powerpoint.

So I found a tip somewhere that suggested to freeze the demo track, cut the remaining tracks (powerpoint + audio) where I wanted the extra time, slide right-hand side to the right as far as needed, export a frame from the PPT track, import the generated image file into the gap, and adjust its length to fill the gap.
This method appeared to work ... except that now during the three seconds I added, the demo appears to freeze too. And at the end of that time period it jumps instantly to where it is supposed to be. So instead of seeing the demo in fluent motion while the audio is silent and the powerpoint slide remains unchanged, I see the demo halt for three seconds, then skip ahead.

I don't know whether this is a bug or intended interaction in Camtasia (I'm a farily new user). But I do know that this is not what I want it to do.
Can someone provide alternative suggestions?

Answering my own question because after posting I did figure out a way to fix this problem.

1. Freeze all tracks except Powerpoint slides, then use "E" (extend frame) to insert the required amount of time in that track.
2. Freeze all tracks except the audio, then cut the track and drag the right-hand version to the right by the required amount of time, so that it re-aligns with the powerpoint.

I still think that it's strange that this has to be this hard; I think there should be a single function to immediately extend ALL non-frozen traks (including audio) by a specified amount, but at least I have a workaround now.

Good for you, Hugo! Nothing like experimenting!
As good as AI may be getting, I don't think it can anticipate every user's personal needs. My guess would be that the developers are trying to add bells & whistles but they're leaving the basic functionality alone. In other words, we can each do what we want, but it takes longer. At least we're playing with a common denominator - someone like me who does a screen recording and then wants to gussy it up a bit.
That's where Kayakman's posts are so useful!
