Extraneous Related Links trailing at the end and could really use the specific role permission to run this.

### Type of issue

Other (describe below)

### Feedback

2 things:
1) there's a RELATED LINKS at the end of the document like it was pasted in markdown to add more, but didn't get finished. Easy fix, low hanging fruit.
2) I could use some help figuring out what roles need to be added to run this cmdlet. I'm trying to follow PoLP, Cloud Application Administrator(Built-In) doesn't have microsoft.directory/applications/update, but I think that it needs it. However, I can't confirm with this document.

Start with src/Resources/Resources/help/Update-AzADApplication.md and the linked Update-AzADApplication documentation page, checking the trailing Related Links section and the cmdlet's permission guidance. Confirm the least-privilege role and required application update permission, then remove the unfinished Related Links content; done means the page is complete and accurately documents the needed access.
