Many themes utilize page builders or developers will install page build

Many themes utilize page builders or developers will install page builder plugins, so choosing a form from the default page/post edit screen isn't the best way to integrate your form embeds.

I would recommend making a page in the Dashboard under Tools where you can login to your account and select forms to embed, or show the shortcode for the form.

How is it that you are able to show forms from your account w/o logging in via the plugin settings?
