How should the value look for the 'other' option in a Radio field?

[Gytjarek]

I'm attempting to send a mutation for a Radio field where the other option is selected. Gravity Forms sendsgf_other_choice along with the input_{$field_id}_value. However, I noticed that the Radio input supports only a single value field in the mutation. How can I bypass this limitation?
mutation { submitGfForm(input: {fieldValues: [{value: "gf_other_choice", "HOW TO PASS OTHER VALUE HERE" id: 7}], id: "1"}) { errors { message id } } }
