How can I switch my gamemode at runtime in one level map?

[keyllll4654]

The gamemode I am currently using only allows me to roam the game scene by dragging with the left and right mouse buttons, but I now want to implement a feature as follows: when I click a button at Runtime, I can also roam the scene through WASD on the keyboard.
My proposed solution is to change my gamemode to third person or first person in the template at runtime.

But I have researched a lot of information and it seems that Unreal Engine does not support me in doing so at runtime. Do you have any other ways to help me achieve this effect besides opening another level?

The game mode doesn’t determine the movement.that’s the pawn’s job.
you could either to change the pawn by using possesse node or implement multiple movement features in a pawn.

you have no reason to change the game mode,it is a game manager.
