How to assign the attribute "teamsId" of a linked entity in formulas?

[cpicanco]

entity\addLinkMultipleId('user.teams', 'id')
entity\addLinkMultipleId('user.teamsIds', 'id')

did not work

Hello,
It should looks like this

entity\addLinkMultipleId('teams', user.teamsIds)

Note: it is not supported for link-multiple fields. Mean that your relation of the custom entity to User should be Many-to-One. Many-to-Many or One-to-Many will not work.
