Connection downloading and importing to different control hub?

Export and import of connection from one control hub to another is possible ?
With command like connections.get_all() . We get only id, type and name . What about other configuration like (url , credential, tags)
And for importing this to different control is also not working as we tried connection_builder mannually providing the values for only id and name . Not sure what to pass on the sdc url? Any suggestions here
