Maybe this tip could be useful ? I use Cloudapp for personal use but it requires you to pay a subscription in order to record the screen for more than a few minutes. At work I am using Camtasia which is far more better but the cost it's pretty high.
I use ApowerMirror to stream phone on PC and record it, there's a guest option there with no signup, you can't record then (only take photos), but you might be able to capture the screen with something like OBS studio I guess?
