How to activate MS Entra Private Access - activate without impact?

Hello,

I'd like to confirm that we can activate Global Secure Access to get access to MS Entra Private Access without impacting or breaking our current Entra/Azure configurations. If so, once activated, what will enabling the preview features impact? We want to try MS Entra Private Access, and as far as I can tell, that is a preview feature. How can we enable it initially without impacting our current environment?

Over here: https://entra.microsoft.com/#view/Microsoft_Azure_Network_Access/Welcome.ReactView?culture=en-us&country=us

it says: "To activate Global Secure Access, click the activate button below. Note activation will not impact any workload in your tenant until preview features are enabled"

So once we activate a preview feature, which MS Entra Private Access is, do we need to expect any weird behaviour and things breaking right out of the gate?

Thanks!
