Update Deal associatedCompanyIds



I’m attempting to update a Deal’s associated company using the API but it doesn’t appear to work or has missing documentation. When creating a deal, the associatedCompanyIds can be set according to:

For example, when updating a deal, I’ve tried using the associations as such:
