Role Checking Before Access

I'm attempting to make a User System from Laravel, and I have a plan to give certain users "BETA Tester" role so that they can access the beta side of the site.

However, I am unsure if this is even possible and how I would even go about doing it.

The sort of plan i'm looking for is 'Navigation To Beta Section Of The Site > Big Log In [SKIP IF ALREADY LOGGED IN] > Check If The User Has The "BETA Tester" role > If Yes Send Them To The Beta Site / If No Tell Them They Do Not Have Access'

Is this possible?
