How to load a project by clicking in a object from another project

I'm working with children, introducing them to Squeak 3.9 and I need to link between two projects.
In one project I've some objects, so, when the user give a click in one of them it loads a different new project I published previously.
Can't find a solution...Anny help will be welcomed.
