multiple apps with dependency to one user written toolbox

Hi

I have a question regarding appdesigner.

I have a use-case where I write multiple apps. All of these apps depend on one (non-app) toolbox that I have written (for example a collection of functions and classes). I know I can add dependencies to functions in the appdesigner packaging gui. If I add the same dependencies in all apps, and then install more than one app, will the toolbox be installed multiple times or only once?

Maybe a solution would be to design the toolbox as a non-executable app?

What could be a convenient way to deploy such an architecture of apps + toolbox?

Thank you for any help/opinions!

EDIT: Nevermind, I just found the toolbox packaging included in matlab
