Spring Boot functionality for Grails 3 projects

Since version 3 of Grails, the framework is built on top of Spring Boot. I discovered that a lot of IDE assistance and features that are available in plain Spring Boot projects are missing in Grails 3 projects. I think these should also be made available for Grails 3 projects, since every Grails 3 project is automatically also a Spring Boot project.

Some Spring Boot related features I found missing in Grails 3 projects:
- "Edit Run Configuration" is missing the section "Spring Boot Settings"
- "Endpoints" (Spring Actuator) is missing in Run view
- Run Dashboard
- Spring view doesn't display AutoConfigurations like in Spring Boot projects

The issue names no repository files or tests. Start by comparing a Grails 3 project with a plain Spring Boot project in IntelliJ IDEA, focusing on Spring Boot Settings, Actuator endpoints, the Run Dashboard, and AutoConfigurations; done means these four features are available for Grails 3 projects.
