Project fails to build from github for another user.

Hello, I have an issue while sharing my project with a collaborator on GitHub.

The project includes plugins that another person does not own, so I’ve put folders of those into the main directory of git and while the project works without issues while I am trying to access them from git on my account on Unreal Engine from another device, when my friend fetches files from git we constantly get this error:

I have seen some solutions of the web, that require rebuilding the project from Visual Studio and I’ve tried to do this but because all is programmed with blueprints in the project, I cannot generate the files for Visual Studio as I get this error:

We tried to put the plugins into the engine of my friend directly instead of being in the project but that did not helped as well.

Any tips how we can handle this issue so others in my team could access the project from git?
