SAP C4C workflow rules- Notifications to Involved party members

Dear Experts,

We have the requirement where :-

1) An email is to be sent to all the involved party members as soon as they are added to an opportunity.

2) Also When the opportunity is won then also it should send the notification to all the involved party members.

Can somebody please help how can we do this via workflow rules?
