How to open a file in another project?

Loading our monorepo as a whole into Webstorm was too slow (indexing was slow and Tailwind suggestions were hanging all the time).

So, now I try to open separate projects, e.g. project one is AppA and project two is the ui package inside the monorepo.

Looks good so far.

But: Is there a way to link between the projects, so that e.g. if  I “Ctrl+Click” a react component from the ui package, the ui project opens with the right file?
 

Thank you in advance (probably to Elena :-) ) !
