How can I display different error messages on my MUI input field?

I have a form input field that displays an error if the user tries to submit while empty, but I also want to show a different error message is the input is not unique, I currently have this

<FormTextField
    className={classes.nameInput}
    errorMessages={[handleErrorMessage()]}
    label="Recipe Name"
    id="recipe-name"
    isRequired
    name="name"
    onChange={handleChange}
    placeholder="Recipe name"
    validators={['required']}
    value={slug}
    autoFocus
/>

This is MUI v4
