Hi @Anonymous Please follow the steps below for multiple users in the people picker field.

Initialize the 'Users' variable to store all the email addresses.

Initialize another variable to store the ';' separated email addresses

Pass the above-declared variable to the below action

You can also use the 'Grant access' action inside the 'Apply to each' which will increase the transaction calls to 'SharePoint'. To reduce that, try to use the above steps.
Hope it helps, please like it or mark it as a solution if it resolves your clarification or issue
