Is this still being developed / supported?

Hey! Cool block! Unfortunately, it doesn’t appear to be in development anymore judging by the Github repo (ironic, I know…) here: https://github.com/audrasjb/embed-block-for-github

As well, when you actually insert the block the links are not clickable and like others said it’s not responsive.

So, here I am posting… is this developed anymore or is this abandonware?
