Integration with Elemailer

Hi,
I am Andrew from Elemailer. We are trying to make an integration with your plugin to be able to give your users option to use Email template with of Elemailer in the email notification settings https://i.imgur.com/NJFu9w4.jpg
So as you can see we need a way to add our plugin’s template list here in the email notification field. We found that you have a filter – “ninja_forms_action_email_settings” which works but only if it’s used under add_action(‘plugins_loaded’, function(){}; ) with a default priority which is 10. Our plugin uses priority 145 in the plugins_loaded so the filter you have doesn’t work with this.
Can you guide us with this integration and tell us how we can load our settings there even if our plugin is loaded with priority 145 in plugins_loaded add action?

Regards,
