I have a flatpak IDE, which uses Deno extension, that extension depends on Deno executable, the Deno executable itself depends on Node.
I’ve found the mount point of the container but it’s only accessible to the root.
If I’ve tried copying the Deno exec and running it but it failed, because Deno depends on Node (while I might try coping Node exec and setting paths, it still feels a bit cumbersome and messy.)
Is the (not yet released) toolbox export --bin functionality in this PR what you’re looking for in principle?
Until that’s released, not sure what the best solution in toolbox is. (Distrobox already has distrobox export --bin if that’s an option for you.)
oh thanks. I have just recently installed distrobox. I’m gonna try it out
Edit: No working 
You can run commands installed in a toolbox from the host using toolbox run deno. They will run inside the toolbox container.
