Thank you :)

Sorry for the inconvenience, you will have some manual how to install this module?

Sorry for that necroposting.

@Isidro-hernndez, this is a snippet.

You just have to add "use Drupal\taxonomy\Entity\Term;" in your file header, and L34->L44 code ;)

Thanks! Just gonna add this to my module!
