Would the inability to delete STS access keys be an issue with listing them together?

Also sts keys need tokens so I think there should be an indication like a type so that users don't go looking for them in apps or scripts (for an audit for example).

Fundamentally they are all the same from an API point of view, the idea here is just to show them a hint. Adding an sts tag might be okay let me see if I can add it cleanly.

The current UI is quite wrong we need to address it.

Would the inability to delete STS access keys be an issue with listing them together?

The API has no contract which requires that all access keys be allowed to be deleted. Service Accounts is our extended implementation in MinIO. AWS STS credentials do not have such a feature, so in MinIO, we didn't implement a DELETE behavior for them, either.
