What is the correct way to pass the useForm hook to another functional component in a separate file?

I have a case where I am using array mode of forms. I have various array form inputs, and I don't want to repeat typing them all in one file as They're all very similar aside from the label and the field name. Right now I create the form field component and then call it various times, passing form as a prop. Is this a correct patter?

For example:

const EditableFormListField = ({ form, fieldName, label, isEditing }) => {
  return (
    <form.Field
      name={fieldName}
      mode="array"
      children={(field) => (
        <div className="flex flex-col gap-2">
          <label htmlFor={fieldName} className="text-xl font-bold">
            {label}
          </label>
          {field.state.value.map((_, index) => (
            <form.Field
              name={`${fieldName}[${index}]`}
              children={(field) =>
                isEditing ? (
                  <input
                    type="text"
                    name={field.name}
                    value={field.state.value}
                    onChange={(e) => field.handleChange(e.target.value)}
                    className="w-full bg-white border border-slate-200 rounded-md p-2 text-md"
                  />
                ) : (
                  <p className="text-md">{field.state.value}</p>
                )
              }
            />
          ))}
        </div>
      )}
    />
  );
};


I want to reuse this in a detail view component and do something like this:

const form = useForm({
    defaultValues: eightDReport,
    onSubmit: (values) => {
      console.log(values);
    },
  });

return (
  <div>
    <EditableFormListField
      form={form}
      fieldName="interimContainmentActions"
      label="D3: Interim Containment Actions"
      isEditing={isEditing}
    />
    
    <EditableFormListField
      form={form}
      fieldName="rootCauseAndEscapePoints"
      label="D4: Root Cause and Escape Points"
      isEditing={isEditing}
    />
  </div>
)
