I have a question about Maven's system

I started the League on pc and I had no problem making and triggering Maven.
On the xbox, Maven appeared in the Marcos region, after that I completed all the maps of that region, made an average of 100 maps and completed 5 conquerors.
I've been through yellow maps in the Marcos region, would I have to activate anything I don't know so that Maven can continue the process of watching the boss fight?

I assume you got and used the beacon already. After putting map in the device you have to toggle Maven on (don't remember control).

Later I do the test, there really must be something to activate. Thanks for the information.
