How to get into a Trymacs Fortnite Tournament

How do games like Raskology or Mitro get into a Trymacs tournament, so what do you have to do or have you done to get there?

You have to have a very good Kd and Winrate.
You should have done very well in pop up cups. (Or in the Champions Division.)
It would be ideal if you were a streamer, but I do not think so.
