Hello,

I am trying to implement an option to unassign person from multiple-person column.

I tried to create this mutation:

      mutation {

        change_column_value (board_id: ${boardId}, item_id: ${itemId}, column_id: "person", value: ${user exist there ? null : {\\"personsAndTeams\\":[{\\"id\\":null,\\"kind\\":\\"person\\"}]}}) {

            id

        }

    }

While assigning working great, changing the value to null when there is already a user there, not working.

Any ideas? Thank you!
