Migrating from locally hosted Roam Graph where are the files located?

I’ve already searched a lot and got a lot done thanks to this forum.
I have a locally hosted Roam graph, I’ve managed to export and modify the dates using the python code.
I still haven’t figured out how to migrate teh locally hosted images though. (i.e. a lot of screenshots that were pasted and now appear as ![](local-asset://Roam/ in the new graph.
I know these must be hosted locally so the firebase crawling isn’t the solution.
I think if I could just locate these files and paste them into a folder in the Obsidian local vault the issue should beresolved but I can’t find these files anywhere on my MacOS system.
Any help would be appreciated.
Thanks!
