Need some sort of visual to sum this up:
https://developer.api.bcregistry.gov.bc.ca/en-CA/oas/connect/
All the flows:
Affiliation by code
Affiliation by Magic Link
Affiliation by delegation
Affiliation for Migration (unaffiliated business, new flow system started) [ SYSTEM only for now ]
Backend insert a row [SYSTEM only for now ]
Good start from John:

It should outline the calls and perhaps the screens someone would see visually
