Notice there's a todo comment in the code? ;) it does need to be fixed and the code says so lol

The install inside app's details does not open the iframe to confirm

@graywolf336 I didn't review the code, I'm reviewing the functionality.
If it's not complete please add [WIP] at the beginning of the PR's title and list the pending items because if Gabriel or the UX team will review the PR they will not read the code!

When bying an app the button get for free doesn't works generating the error:

It's a draft pull request, which is used to indicate that it is a draft and not fully ready. There is absolutely still a lot of work to do, a large portion of which I have knocked out and have already addressed.

[graywolf336]

This pull request was not intended to be review ready but was simply to show the current flow, of which the reason it was created in a draft status is because it is not working functionality wise.
