shopify custom app if not showing open app button after installation

If a Shopify partners account is mine and I got the store via collaborate access from the client. Now, I want to install and run my custom app on that store. Can I??

The app is developed in PHP template as it’s coded in Laravel + React framework my app is working I’ve tested in local even on development store it’s working I just want it to shift on client’s store but I’m not getting “open app” button out there.
