Hi @AdalbertoMoz, thanks so much for taking on this work! 🙌

I gave the code a look and ran inv new-db, and can confirm that everything is working perfectly.

I just have 3 small pieces of feedback that I think will wrap up this factory nicely.

If you need any help or have questions, feel free to reach out. I'd be happy to work through it together 😄

Hey @danielfmiranda, thank you so much for your detailed PR review! Your feedback is always incredibly valuable.

I've implemented your suggested changes in this branch and it's now ready for another review. 🚀

Note: I just changed the PR description to include the new Review App link where you can find the latest version of the AppInstallPageFactory
