How to programmatically trigger validation on a field in 'react-hook-form'?

Question

I try to do it like so, but it does nothing...

import {useForm, FormContext} from 'react-hook-form';

const formMethods = useForm({mode: 'onSubmit'});
const {triggerValidation} = formMethods;
triggerValidation('myFieldName');

return (
    <FormContext {...formMethods}>
        //here are my form fields, one of which has the key of 'myFieldName'
    </FormContext>
);
