Auto population of fields

[Community Alums]

Hi community,
So I have a requirement I need a client script for my variable set which has few variables the first variable is "is_this_request_for_you" which is yes/no type. By default it is yes and that time the requested_for variable is not seen but in backend it should populate with the current user name. If the user selects no then the requested_for variable is shown and user can the choose the person they want to want to choose. the rest variables are line_manager , location , contact_number which shoudl auto-populates based on whose name is present in the requested_for variable which could be the current user or someone else whose name is mentioned

Thank you in advance for helping
