Hello @Anonymous ,
I have created laravel Shopify app. to authenticate the app in fields App URL and Allowed redirection URL(s) we have to add (authenticate) in the app URL then after installing the app. when it is open in the admin section the show the blank page.
And if we removed the (authenticate) from (App URL) the app shows a 404 error at the time of installing the app.

So help me how we can remove (authenticate) from (App URL). without 404 error
We are using the below versions of packages.
Using Osiset version: 16.0.0
Laravel version: 7.2.9

Thanks
