In the Integration Assets page and also the Peers page, we have permissions lists that could be shortened. Would you mind making those changes?

Instead of:

• Operators can create...
• Operators can view...
• Operators can edit and delete...

We can do:

Operators can:

• Create assets...
• View...
• Edit and delete

I'm not sure what is meant by "referenced". I did a super quick search and I don't see "reference" being used anywhere else (other than in the list a bit below) in this context. If that's the right word to use, then that's fine.

[brad-dow]

This verbiage came from a deeper dive into how deletes actually work, but it doesn't sound very natural. Basically, that delete mutation checks (at the database level) if any peer or wallet address record is using an asset's id as a key.

I have some similar content in the live version of the admin user guide - https://rafiki.dev/admin/admin-user-guide/#delete-asset

"Reference" is used twice here and "associated" is used once. Let me find a smoother way to match similar phrasing - maybe something like "...if the asset is not associated with any peers..."

Ready for technical review - adding @mkurapov and @BlairCurrey as reviewers
