Hi,
I was just wondering if this works for 1.16.5 and whether the commands are op level 4 only or able to be set to that?

Oops, I somehow did get/see a notification for this issue being created. Afaik, the code as of commit caea75b should work with 1.16.5.

The current latest release works with 1.17 and has not been tested on 1.16.5.

ATM, the commands can be used by anyone. In the future, I may integrate with permissions managers instead.
