Hello, I am currently building a PowerApp Holiday Booking system. Once the booking requst is approved, I would like to create a calendar appointment on requestor's calendar automatically. I have used Create event (V2) and it successfully created an event. However, I have now following questions and I do not know whether these are as designed or any other option I can use to achieve what I need.
1. Even though I set the Response requested to No, the requestor still receives an email asking him/her to accept/decline this calendar event. Because this request has already been approved, I would like it to automatically created in requestor's caledar rather than ask to accept/decline

2. As shown above, the organizer is always showing my account (I built and deployed the flow), does that mean I need to use a service account to build/deploy the flow?
3. It's always showing Subject; Organizer? If I use service account, does that mean it will show Holiday; Service Account on people's calendar?
4. Am I using the right action? If multiple users have booked the same day, does that mean multiple events will be created on the service account's calendar (each event has different attendee (requestor))?
Thanks!
