Get List of vertices of a creative prop for verse

I made a platform by merging a couple of hundred 128x128x128 blocks. The shape of this platform is complex. I want to make a function that teleports you randomly onto one of those blocks from this large mesh. To do that I need to get the 3d coords of each block and randomly pick one, or do some other kind of trick with making a convex hull or whatever.

So my question, any way to get a list of vector3’s of this mesh, like all the vertices? Otherwise i’ll have to create a []vector3 manually by typing in like 200 3d positions relative from the gizo or centroid or whatever myself.

Screenshot of the platform, simplified from the top, this is a single prop.

Another way to put it if you don’t understand. Let’s say I have this mesh in my map, I need a verse function that returns the highest vertex point of this mesh
