Very simple way to create dynamic widgets for the storefront or without having to create a custom app

I just had a quick look so far. It is what it promises: This App provides you the API keys in order for a different storefront like Vue Storefront.
The guy who rated this 1 star clearly has no idea about this. Doesn't mean its bad. I gave it 5 stars just to correct that 1 star recommendation.

I'm utterly confused about what to do. This isn't an easy app to work with. This is a sales channel and yet I have no clue how to proceed other than entering the info I did. When I go over the app it was confusing. I'm just a shop looking to build traffic and sales, that's it.
