How can I grant permissions to a group on gamemode spectator and survival? But so that the player in the group could not use creative, adventure.

This entirely depends on your Server setup and not LP itself, as it doesn't manage the gamemodes of players.
If you use a plugin like Essentials(X) that manages the /gamemode command, check its documentation for the command permissions.
If it is the default vanilla command, then the permissions would be minecraft.command.gamemode

Note that vanilla /gamemode doesn't have permissions to restrict it for specific gamemodes only, while EssentialsX does.

Yes, I have essentialsX, but I did not quite understand where to enter the permissions.

I issued such permissions for the players. But it still doesn’t work

No . at the end. Also be sure to click save and to run the command it shows after clicking save.
