At the moment it seems not be possible to add or update other phone numbers like (mobile, work or private) or emails via workflows or api (including Zapier, Pabbly, ...).

There is only one field available for the phone number. (See Screenshots)

This is very problematic and because of that it's not possible to sync contacts between different systems like google contacts or O365.

It would be great if we would be able to pick the type of phone number or email via api or workflows.
