How can I embed a View inside a content of a node?
Option 1
You can create a View Block. Then the view block will be available in the blocks section. Assign the view block to a region and show it on specific pages if you need to.

Option 2
Create a twig template file for your node and use
Twig Tweak

Twig Tweak module provides a Twig extension with some useful functions
and filters that can improve developer experience.
Ex:    &lt;dd&gt;{{ drupal_view('view_name', 'page_1') }}&lt;/dd&gt;

Option 3
If you use Panels or Display Suite, you can embed the view as a field.
