Give Pockets their own URLs. This would work as follows: the URL takes you to a metauni webserver, where you authenticate your Roblox account (the first time, after that it is stored), and it sets a flag in a DataStore to say which pocket you want to go into. The webserver then redirects you to the Roblox URL for say TRS. You click "Play" and enter the server, once you're inside it checks the DataStore and forwards you onto the desired pocket.
