Email notification to Client regarding access request status with reasons

Currently, an email notification is generated automatically to client that their access request has been rejected.

To better serve client regarding their request status, an email notification will include the following info:

Scenario 1: Access Request has been rejected
GIVEN Client submitted the Access Request to specific product that require BCOL Admin to review and approve
WHEN BCOL Admin reviewed and rejected the request based on Client's account set up
THEN an email notification will be sent to notify Client that their request has been rejected (with reason)

Scenario 2: Access Request has been reviewed/rejected but client provided additional info to support their request
GIVEN Client have the additional info and go to their Product selector and submit their access request again
WHEN BCOL Admin go to review the request from Pending column and approve the request
THEN an email notification will be sent to notify Client that their request has been approved (without reason).

The reasons (TBD):
Rejected with reason (BCOL Admin to provide?)
Approved

Jan 24, 2023 - met with BCOL Admin and agreed to have the option for them to enter other reasons (50 characters max.)
