        res = super(CrmLead, self).convert_opportunity(partner, user_ids=False, team_id=False)
        
        activity_vals = {
            'activity_type_id': 2,
            'display_name': 'text',

        self.create_activity(activity_vals)   
    
        return res

    def create_activity(self, activity_vals):
