Since currently there isn't any mechanism (thankfully, tbh) to teleport to the dimensions in-game, i suggest the addition of a file to specify a custom portal for modded players that have Datapack Portals installed.
Basically, create a .json file under <datapack.zip>\data\backrooms\portals with a structure like this:
...with more arguments like kind of item to be used to activate the portal (either flint and steel or water bucket) in the mod description in Modrinth linked above.
I don't think the presence of that .json file would cause problems in vanilla/non-modded, since it doesn't overlap with any other file read by it. So, the datapack will continue working as usual for those that doesn't have that mod installed.
