want to implement list collector in servicenow workspace

[shrngikaG]

want to add multiple users to the group at single click after selecting from list. How can it achieve in customized workspace. 

[PritamG]

allow users to select multiple users then add a button to trigger the action. capture selected users and call a script include or flow. use GlideRecord to add selected users to the group (sys_user_grmember) then update the list dynamically.
