Pop ups also possible through this plugin?

I’d like to also use pop-ups on my website. I created a few in MailerLite.
But after installing the plugin, I only have the option to choose the embedded forms, I cannot pick a popup.

And through the code provided in MailerLite I have also not been able to publish a popup.
I’m using WP Bakery Page Builder and put the code in the Raw JS box. But it’s not working.

As Mailer Lite is saying, when picking the code from the popup, it should be possible through the plugin. After that I tried the plugin. But I’m not getting to an active popup. Hope someone can put me in the right direction
