Install dev custom app embedded and extensions on non-development store for testing purposes

[WarrenWolff]

We have worked on a Shopify app that has both app bridge embedded which can be used on the admin panel on the left side, and as well, some extensions both app blocks and app embedded.

We have arrived to at a good point in development, testing within development store went very well and we wish to try the app on a production store even if the app is currently in development (not listed, neither approved). So, the chosen distribution method is Custom app for a targeted customer store.

After installation, we could find the app bridge embedded part working but NO app extensions, when accessing the theme customization there were no app extensions.

Is it possible to install app extensions in development using custom apps?

For those that will find this useful.

After having created the custom app and installed it on any production store to have the app extensions, wether they are blocks or embedded you'll need to deploy.

So, run "npm run deploy" and push your first version, after having done so, you'll see your extensions automatically customizing the theme within the visual editor.

And also, everytime a new version is deployed those will be updated.
