Hello Everyone,
I am attempting to use the "Send an HTTP request V2" connector from Office 365 Groups. However, when I execute it.
Flow set up:

I encounter the following error:

To track the new ID of a recently created plan in that instance, I have set up a 'Compose' step. When I execute the same request using Graph Explorer, everything works as expected, as illustrated in the attached image.

I'm uncertain how to resolve this issue. I am aware that I could use a different HTTP request and attempt another method of authentication. Nonetheless, I would like to understand why the current setup is not functioning. Specifically, I would like to know which security settings I might need to adjust.
Any guidance would be greatly appreciated.
