Hi!
Glad to hear my suggestion was useful.
REgarding your new question, I am just an average user in MS Forms, sorry. I don't remember any action block allowing PA flows to inject a prompt on an MS form, but in this link you will find Microsoft Forms connector official doc:
https://docs.microsoft.com/en-us/connectors/microsoftforms/
Just guessing next steps to proceed:
a) Keep on investigating if this feature is available in Forms via PA, or
b) Did you consider implement the questionnaire with a Power App instead of a Form? For sure this way you can offer real time interactivity with end user
c) ...
My humble suggestion:
1.-Mark this topic as "Solved" by clicking "Accept as a solution". THis way others with the same problem can find a solution faster

2.- Open a new thread for your next question, no matter you opt for a) b) or c), following the policy: 'One Question, one post'. This way you have more chances to get a useful insight, since both volunteers and Microsoft Support staff tend to pay attention to unanswered posts
3.- (OPTIONAL) Click on 'Thumbs up' in any answer to this current topic you found valuable.

Even though this 3rd step is OPTIONAL, please remember it is the cheapest, easiest way to say thanks to somebody that simply tried to help. And just between you and me, everytime an inspiring answer receive a kudo, an ewok escapes from The Emperor menace 😉
Thanx!
