Force TestFlight notification to testers after expired build

Hi.

I have an app which expired = more than 90 days without a new beta being uploaded to TestFlight. After these 90 days, many testers switched to the last (stable) App Store version since the installed beta became unusable.

Now, after I released a new beta, I noticed that 90% of the testers didn't install it.

Is it possible to force a TestFlight notification or send an automated email to the testers that a new beta version is available for download in TestFlight?

Many thanks,
