How are you supposed to get an Admin API access token now?

Trying to integrate LiveAgent with Shopify and it needs an API key and an Admin API access token. This used to be straightforward: Getting an API Access Token from Your Shopify Store | StoryChief Help Center

But these instructions no longer work because Shopify completely changed the App development section.

I can go into the new Dev Dashboard thing and get an API key, but an Admin access token is nowhere to be found.
