kglitch , 11 months ago I use Thunderbird for this, it syncs with Google Tasks. It's a bit janky but works. Here's a screenshot of how it looked 4 years ago (not much has changed) https://www.ghacks.net/wp-content/uploads/2019/10/Manage-your-Todo.txt-with-Thunderbird-using-this-extension.jpg It's been a while since I set it up but I think it starts working automatically when you connect your Google Calendar to the Calendar in Thunderbird.
