Why does apm_user have access to TPM Lifecycles but apm_read does not?
Based on our Product team's response, the following was mentioned:
Business Stakeholder (sn.apm.apm_read) is a low-cost License that gives read-only access to reports.
The TPM UI is NOT categorized as a report but is rather a custom-designed UI where a user can perform several additional actions and so TPM UI access is NOT given to the sn_apm.apm_read role.
This is expected behavior and the required role is "sn_apm.apm_user".
