OAuth 2.0 Setup - Create Permission Set to grant access to External Credentials

Create a new Permission Set to grant Salesforce users access to use the External Credential created earlier for Jira connection. For more details on how to create a new permission set in Salesforce refer to Create Permission Sets.

In the permission set, edit the External Credential Principal Access

Add the “zc_ec_j00_admin - int_user“ to the Enabled External Credential Principals section and Save

Note: The name - zc_ec_j00_admin - int_user may be different when connecting to multiple Jira instances. j00 refers to the first Jira connection

Finally, assign this Permission Set to all Salesforce users who will need access to Jira actions (including at least the Salesforce user that is configuring zAgileConnect)
