Powershell alternative to allow applications to access online meetings on behalf of a user

Hello ,

I'm trying to use Microsoft graph API in my applications to allow users to create online meeting using the application token.

I followed this tutorial where it is mentioned that is required to create an application access policy and grant it to a user.

It's working perfectly using powershell.

My problem and my question : is there any other way to grant a user the access to create online meeting without passing by windows powershell ( like using microsoft graph api, admin dashboard ) because i can't ask my clients to execute commands on powershell to give onlineMeetings to a user.

Thank you ,
