Invoke-RestMethod : The remote server returned an error: (403) Forbidden.

I get the following error when I try to run New-DCConditionalAccessPolicyDesignReport
I used a User with Global Admin rights, but it still gives me an Error 403. Is this a permission issue? What should I change?

I am running into the same issue using New-DCConditionalAccessPolicyDesignReport, DCToolbox 2.0.2 from PowerShellGallery.

If I try using PoSh 7.3.2 I get a different error..

VERBOSE: Generating Conditional Access policy design report...
Invoke-RestMethod: {"error":{"code":"ResourceNotFound","message":"NamedLocation with id xxxxx does not exist in the

Looks like one of my CA policies had a stale location exclude, once I updated the CA policy and re-run DCConditionalAccessPolicyDesignReport it worked without issues.
