Hi David, thanks for your reply. on Power Automate I am creating an approval workflow based on a sharepoint list.
the group members are more the 100, but only one user should approve the new item when created in the sharepoint list. probably I solve, I need to check/test, first I add one action the "List group members" office 365 groups, in order to select my sharepoint list, then I add another action Filter Array in order to select only the specific email adress to be used for the "Start and wait for an approval" action
