godot 2D navigation baking

Question

I'm not too new to Godot but also not too advance. I've looked around for quite a bit
but I couldn't find good resources on baking navigation regions in 2D
I understand that the 2D navigation polygon inherits from the 3D navigation mesh

I want to dynamically at run time add or removing regions of the navigation region 2D node
preferably it would work with Tile-maps (but i heard they are a little iffy for that)

the closest thing i found was a brief explanation of the theory in another post [https://github.com/godotengine/godot/issues/60546#issuecomment-1144634908]
but I was unsuccessful in following these instructions to work

any help is much appreciated

Answer 1

godot contributor has made a working fork with navmesh runtime baking for navigation region 2D, 2 months ago
it is still not on the live branch as of writing this.
