I believe you can add it to functions.php

For future viewers with the same problem, this plugin depends on lodash, but apparently it does not ship this dependency, I manually added lodash to the admin scripts and it worked fine

/* Custom script, enqueued in the *ADMIN* header */
add_action('admin_enqueue_scripts', 'utils_admin_init');
function utils_admin_init() {
  wp_enqueue_script ( 'lodash', "https://cdn.jsdelivr.net/npm/lodash@4.17.20/lodash.min.js" );
}
