If I understand your challenge correctly you now have 1 Mendix project that has 2 modules containing the pages. 1 page in module 1 Landingpage and the other in module 2 the InstallModule and you are trying to open the page Home from module 1?
And this does not work, the Home page is not opened when clicking the button?
As you imported the module the permissions might need to be set in the security section to allow for the used userrole to view the page in the newly imported module.
With the link button you can open links and the properties look like this:
With an open page button the properties look like below and I think this is what you need:
If both modules are in the same project, just use the ‘Show Page’ action to open the Recipe page from a list of Recipes on Home.
If you're talking about different projects than you need to set the URL on the Recipe page and use that in your Home project to navigate to. But you need to think about different environments (test/acceptance/production) to get the right URL and you might need deeplinking and authentication. That seems a couple of steps to far for now, based on your question. I would advice to get a developer with some experience in Mendix.
