Alert - Custom Probation End Date alert to assignment Line Manager

Summary:

The custom projected end date alert is failing in case of Multiple assignments, when two assignments with different LMs satisfy the criteria, the display name token in the alert body is printing both the LM names. Has anyone faced such issues or knows if there is right token to use for assignment LMs?

Below is the token used.

${AlertUtils.toString(AlertUtils.empManager(workers.workRelationships.assignments[0].AssignmentId).DisplayName)}
