Not getting my app on site of my development store

I have created the custom app and installed it on my development store but not getting any button on the site of the development store. I want my app on customer’s site like this

but after installing my app I didn’t get a button like this can anyone guide me?

I assume your app adds a script tag to the page. If so these are the two starter questions:

  1. Was the script added?
  2. Was there errors?

Without an example that will be a little hard to troubleshoot.

didn’t add a script, can you please tell me what is the script required for
this and where should o find this script for implementation

I have developed a site with react js for the Shopify app and created one public app using that site. Now when this app will be installed on the development store I want that my app will visible on that site but not happening now I haven’t write any script that can you please help me with how to do this?

Hi there,

The UI of an app is intended for the store owners and not for its customers. Either as an embedded Iframe inside Shopify Admin or an external website that integrates with Shopify.

In order to modify the storefront UI you will need to create a javascript and register it with Shopify ScriptTag feature or automatically modify the store’s theme (less recommended unless there is no other alternative)

you can read more about it here or here

Good luck!
