Using the Pods Framework, I am trying to get the underlying type of field for a custom pod. I need to determine:

1. if it is a relationship field
2. if it is a single or multiple relationship field

I have tried ['type'] using $type = $field['type']; but don’t get any results

function get_relationship( $atts ) {
    global $post;
    
    $defaults = array(
        'post_id' => $post->ID, // default to the current Post ID.
        'pod' => '',
        'field'   => '',
        'classes' => ''
    );
    
    $args = wp_parse_args( $atts, $defaults );

    // get the pod
    $pod = pods( $args['pod'], $args['post_id'] );
    
    // get the relevant field
    $related = $pod->field( $args['field'] );
    $type = $related.type; //['type']; // ?
