gamemode group change

[surpasser]

Hello!
I am looking for a script that would change a player's group automatically , to default if he is in game mode survival

- i use the group manager, so the command is ' /manuadd %player% default '
- version 1.16
that's all..
i tried my self making it but i have 0 experience with skript..

Thank you!
