I wanna create a "domain_force" with a complex condition (with me). That is a sale person can read, update (write) but not delete records of an other sale person if the in a team. And delete permission will be available only for own records

my code (need to update):

Verify team sale['|', '|', ('user_id', '=', user.id), ('team_id.user_id', '=', user.id),('team_id.member_ids', '=', user.id)]  

I need your help because I don't really understand '|', '&', '&amp'. Thank you so much
