How do I change the uninstall message for an app I'm developing?

[den232]

I can see the message in the admin graphQL API, as 

{
  app {
     uninstallUrl
     uninstallMessage
  }
}​

 which produces this:

{
  "data": {
    "app": {
      "uninstallUrl": null,
      "uninstallMessage": "You’ll no longer be able to use this app, and its associated discounts will be deleted."
    }
  }

But how do I do a mutation? to change it.  I'd like to say to use the in-app button first!

Thanks jb

dear Dora-Felix,

What a quick reply! ... I do have a problem.   Dumb perhaps, but still a stopper for me.  Once I navigate in the partner dashboard to the app I'm developing, I do not see "App Setup".  I have several options on the left:

• Overview 

• Configuration
• API access
• Extensions

• Versions
• Distribution

• Insights

These each have their own pages, but none have app setup ... Shall I send you some screenshots? 

Cheers and Thanks jb

Anyone have a suggestion?  All I got was a scam/spam response that has evidently even been deleted now!  Thx  jb

Also ...

I am building the uninstall feature for my (new) app.

A merchant taps my button to say "uninstall this app" ...

First, I will do some metafield (etc) cleanup to his store, then want to do the actual uninstall.  I see some references to how to do this using the rest API, such as https://shopify.dev/docs/apps/build/authentication-authorization/app-installation/uninstall-app-api-... but that API is going away soon, so would not be a brilliant choice ... right?

How can I do the actual uninstall by another API?

Thanks!  jb
