Form「users」's 「Import Users」 function with error "Authorization Required"

I am encountering an issue when using the “Import Users” function in the D365 Users screen. Every time I try to use this function, I receive an error message saying “Authorization Required.”

If this is a recently created DevBox, MS does not link those to your tenant since Nov 2023. There is an article out there regarding this.

Thank you! I will try setting up the new environment based on the MSDN “Secure one-box development environments - Finance & Operations | Dynamics 365 | Microsoft Learn
