Is it acceptable to create a custom TestFlight badge for an app and utilize it?

I've published my app on TestFlight and enabled the public beta link, allowing users to try out the app and provide feedback.

I'm considering creating a custom TestFlight badge (Like this - https://askyourself.app/assets/testflight.png) for my app, linking it to the public beta link, and embedding it on my website. Is this an acceptable practice?
