1. Create an app registration in Azure Active Directory (Can also create from SPO using _layouts/15/appregnew.aspx)
  a. Under "Authentication", make sure implicit grants are all checked (access tokens and id tokens)
  b. Under "Certificates & secrets", create a secret (jot it down!)
  c. Under "API permissions", add SharePoint appropriate permissions
 
2. Go to SPO instance app inventory: https://<tenant>.sharepoint.com/_layouts/15/appinv.aspx
  a. UNKONWN: in order to create the app registration on SPO, a secret is required. For some reason, the secret created in the previous
     step (1b) is not the correct format. I've generated a secret and re-created a secret using 1b. I THINK, both secrets would work, 
     but in my test case, i ended up using the 2nd secret I created under 1b.
  b. Fill in details and add permissions xml (https://docs.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs)
