Provide Google Analytics 4 access to one subdomains data only

My web app gives each paying customer their own private subdomain, e.g.:

• customer1.mysite.com
• customer2.mysite.com
• etc

Currently all subdomains use the same GA4 tag. No properties exist.

Is it possible to give an employee from "customer2" access so they can only see their subdomain's data?

Thanks

I don't think it is possible.

Instead, I linked Looker Studio (from Google) to Google Analytics 4, and was able to create a report for a single domain. Then I was able to share that report with the customer.
