(Question) How to make change group rank gui?

I have problem. How to make change group rank gui?
I tried to find a solution to this in many places, but it didn’t work. Also, I am not good at writing scripts, so it is too difficult for me to solve this problem.

How can I make it?

Help me…Too difficult…

You need to use some sort of API and create a ranking bot.

I don’t understand. What do you mean with ‘change group rank gui’?
Are you trying to make an overhead gui that displays the player’s rank in a certain group?

I’m looking for a way for only people who join a group with gui to change their rank in that group.

Hmmm, maybe this topic could be useful for you:

You need to use some sort of API and an account which will be used as a Ranking Bot in your group.

I found this video you may find interesting to make a ranking bot and link your API.
