I made a conference call with 4 groups that used "realtime database". All data about groups/users/admin added now in the code manually and after a run, they will add in firebase.
Then, I made an admin panel to send a new group's data (groupID/sinch API keys/admin's data).
I want to change code to use of this data that are adding by admin panel in firebase.
Please see screenshots of "realtime database".
