CRM module is untouched, means not any customization made yet.

please help in writing domain filter for Record Rule to get all user's data whose Manager is currently logged-in user including his/her data in CRM leads. what i have tried yet, mentioned below with errors it is showing.

['|', ('user_id.employee_id.manager_id', '=', user_id), ('user_id', '=', user_id)]

ValueError: : "name 'user_id' is not defined" while evaluating
"['|', ('user_id', '=', user_id), ('user_id.employee_id.manager_id', '=', user_id)]"

['|', ('user_id', '=', user\\.id\\),\\('hr_employee\\.parent_id\\.user_id',\\ '='\\ ,\\ user.id)]

raise ValueError("Invalid field %s.%s in leaf %s" % (model._name, path[0], str(leaf)))
ValueError: Invalid field crm.lead.hr_employee in leaf ('hr_employee.parent_id.user_id', '=', 2)
