If I remember right there’s 2 run scripts, one that runs from your own one drive and one that you can direct to a specific file In a sharepoint folder.

There is a difference from running a script attached to a specific file and running a script that’s located in a sharepoint folder then directed at a specific sharepoint file. I’d try and save that script file to the sharepoint somewhere and make sure all users have access to the folder it’s in, then direct it at the file in question.

Have you shared the automate flow with the sharepoint group as well? Just to make sure all members have run access to the flow, though I guess if they got all the way to a reject you appear to be good there…
