This is the respective issue for the feature that went into D10.1.x core with https://git.drupalcode.org/project/drupal/-/commit/4dbf3f46c19766a38c3e4... (issue | change record).
Problem/Motivation
...
Use case: As a site moderator, I'm able to use a View, located at /articles/moderate, with VBO to bulk approve/decline articles. I want to access this moderation tool using the admin theme in the same way I'm using the node edit page.
Proposed resolution
Add a new page setting "Use the administration theme" in the page display that allows site builders to make that page an admin one, similar to https://www.drupal.org/project/page_manager.
User interface changes
- View edit page: Page settings

- View edit page: Page settings (with an admin/* path)

- Modal 'Administration theme' form
