I have a development store and want to create a custom app to be used by this store only. In the store’s admin, when I go to Settings → Apps and sales channels → Develop Apps → Create an App. I get the API credentials and can make calls to the REST API to extract information. However, I can’t figure out how to add a link to the admin side menu for this app.. ie, i want to have polaris pages so the client store can enter site specific information or click buttons to run jobs manually, etc.
I know how to do this with an app I create in the partner’s dashboard during the installation process. But adding one of those apps makes my development store non-transferrable (I found that out the hard way). And this app doesnt need to be released to other stores nor the app-store.
