The sample as it is is very complex and also suggests non-secure practices, such as granting admin access to Policy.ReadWrite

Existing sample:

1. Creates 3 dummy CA contexts in AAD but doesn't associate them with any issue. This requires a powerful permissions and the sample suggests to pre-authorize for it.
2. Dynamically loads CA Contexts and presents an admin screen, allowing the CA context to be associated with a website action (POST todo item, delete todo item)
3. Stores this association in a relational database !!!

Proposed simple experience:

• Rely on a static list of AuthContext and actions and no DB
• Just showcase how to do the auth challenge to get MFA, for example on the "Delete" action.
