Authorized domain for local setup

I would love to use this plugin to display photos from our google drive. I’m following the steps on: https://napoveda.skaut.cz/dobryweb/en-skaut-google-drive-gallery/en-get-google-application – but confused by the Authorized domains section. I have entered in my production URL, but how do I enter in my local URL (I’m developing/testing locally). I’m using WP Local for my server. My local url is myproject.local – but it’s not accepting that.

Thank you
