Unable to add multiple approvers in Requisition Approval Data Set

Summary:

We're deploying Requisition approval rules based on Mapping Set.

We created Approval Mapping Data Set where in column APPROVERS we try to add multiple approvers as per Oracle Doc (provide comma-separated usernames)

but we see that column is limited with 30 symbols so we cant add multiple users.

Please advise how to handle multiple users in one mapping data set line
