Hi,
I saw a few posts regarding this but I have a different case. I have this created.

What I want to do are the following:
1. My name appears as the creator of the post, but other people will also create other tasks. The POC/Respondent's Email or the person who created the task should appear as the poster.
2. In the notification, my name appears too. I want to change that as well.
3. Is there a way to edit the notification message in Teams once the post is created. It says URGENT all the time, and the priority is not all urgent. Some are Low. Can I customize that notification message?
