8 – How to render a block in a template?

I've installed the module "Shariff Social Media Buttons" for "Drupal 8":

https://www.drupal.org/project/shariff

Once installed, add a block in:

/ admin / structure / block

I want to display this block in a template:

https://www.drupal.org/docs/8/modules/twig-tweak/rendering-blocks-with-twig-tweak

I have tried with the following code:

{{drupal_entity (& # 39; block & # 39 ;, shariffsharebuttons)}}

But the block does not work (it is not rendered on my page)
