How can I add menu to integrations for internal use.

I'm planning to release an in-house app and would like to be able to run it from the right-click integrations menu.
But the added menu doesn't appear in integrations for the other users under the same enterprise ID

Only the user who registered the integration can display the menu.
It cannot be viewed by other users (including the user who registered the app).

Since it is an in-house app, I do not want to publish it via the app store.

Is there any way to work this out?

The settings of the app are as follows

Dev Console> My Apps> (App I wanna publish)

General Settings
  App Type: Custom App, User Authentification(OAuth2.0)
Configuration
  Enable Integrations: On
Integrations> (Integration I wanna show)
  Permissions Requirement: Download permissions are required
  Display on shared pages: On
  Integration Status: Online

Admin Console> Apps> Custom App Manager > User Authentication Apps tab
  I entered the Client ID and added the app. It went well.

I've found this. but there is no clue.
