I Created the Groups to Segment Instructions, Not all the Instructions were included, and decided to select the ones related to user activity instead of admin (validator).

For example:

The user requests to delete (RequestDeleteAccount)
The request is accepted by the admin (Crank)
The admin deletes the account (DeleteAccount)

Another Example is when an account is created it calls more instructions, I focused on the most relevant to highlight user activity.
