How to insert template block (.phtml) in the Magento 2 WYSIWYG editor?

Use the following code to insert the template block in WYSIWYG (Important! add it in inside double curly braces): 

block class="Magento\Framework\View\Element\Template" template="Magefan_Blog::content/block-template-example.phtml"

The template identifier VendorName_ModuleName::some-template.phtml should be changed.

Attention! You can not use the block tag in the WYSIWYG product and category attributes. To make changes, install the magefan/module-catalog module.
