We have decided to split up

My husband and I have decided, after three years of considering (including relationship therapy) to finally split up. We have three young kids and we would like to maintain our relationship is parents for the children, also after the divorce.

We find enough tools with the mediator for after the divorce when we both will go our own way.

Does a therapy exist for after a divorce where both parents have the intention to stay in a good connection as parents for the children? I can not really find it.
