Stopping collision with polygon internal edges

Godot Version

Godot Engine v4.6.2.stable.official

Question

Does anyone know how to remove the internal edges connecting the points of polygons in tilesets or at least know how to stop the player from colliding them when using one way collision? Sadly I cant send images due to being new to this site, but I can say that I’m trying to fix this in order to continue working on my 2d sonic fangame idea, or at least getting the physics to work first before anything else
