Easy route. Get to the MH UI New Beta page and choose Apex Legends. Click load and a pop up will appear telling you you need to be in one of these groups. There is a "go to topic" link after the list. Click on that and you will be sent to the member groups and features page. Read the rules needed to get to be a member. Example is when you have 50 messages plus with two days old or more account, you get to access League of Legends hack as you will gain confirmed membership. Enjoy!
