how many environments are working with Project for the web in my O365 Tenant?

Hello everyone.
I would like to know and know how in an automatic way (script, flow, etc.) I could know how many environments within my Tenant with O365 are using or have installed Project as an application to be able to use Project for the Web.
As by default when creating a new environment it is not installed project, for this reason I would like to know how within the organization which existing environments have installed the project application.

Any idea about this?

Thanks in advance!!

Kind regards and Happy New Year!
