I have a column in my Users sharepoint list with a column name of URater

with a data type of Person or Group that allows multiple selections

Then I've created a form with a data source of Header because I want to add a data based on the raters listed

I was wondering how I can add default selected items to this combo box based on the raters in my Users list
Note:
I've set a variable in order 2 get all the data in the users list based on the logged in email

This is what I've tried so far

Thanks for the answers
Best regards,
