We have this Capital Request Setting SharePoint custom list >> which contain a Tile field and a People/Group field (which allow multiple selection named Person):-

and inside our Power Automate we are getting all items from this list >> then we need to build a semicolon string for all the user;s emails for the item which have its title = "Board of Directors". is this possible using union and select? i do not want to define an Apply To each if i can do it directly using Select & Union ? any advice?
Thanks
