HTML Game inside Construct 3 game

I wanna put some games in one C3 project.

I want everything to be according to these parameters:

1. The game shell must be C3, for launch, selection menu, and so on

2. No launching from links. All projects must be within one so that you can play without the Internet, so uploading to the hosting and copying the link to the iFrame plugin is not an option

3. The project is done without programming

And so, I managed to put the C2 game exported in HTML into the C3 project folder as third-party files. After a couple of plugins, I managed to try to launch the main file in iFrame and... Black screen. No results.

Who knows how to fix this?

You don't need ajax,

just use iframe navigate to "betaframework/bfindex.html"
