Kindly provide an example how is this flow to be constructed to assign a member as an admin of the group.
Do not send me to Graph website to figure it out by myself by trial and error - this is a paid product and the question is, simply, how is to be used without wasting my business hours.
the fact the Power Automate is a paid product doesn't mean that you don't need to learn it. Just IMHO.
Its a paid product, but this is a volunteer support forum. So you are asking us to waste our business hours because you don't want to try to learn something for yourself. Here's a walkthrough on how to remove a group owner. Adding one uses the same steps and syntax, but with a POST action instead of a DELETE.
I like how when you buy a Windows operating system, they send a Microsoft employee right to your house to walk you through each and every step of Windows, and how to use it in every scenario you might face, because it is a paid product. Such a great feature.
Wait ... they don't do that?! 😮 What a world we live in.
+1 to @Pstork1 's "So you are asking us to waste our business hours because you don't want to try to learn something for yourself. "
I answer questions on the forum for 2-3 hours every Thursday!
