drop_auth() generating short lived tokens

I was using rdrop2 in a shiny app, and had the shiny app creating multiple .csv files in my dropbox account for a couple of months.
Last week I accidentally pushed my dropbox token to github, so I deleted the rdrop2 app from my dropbox account and created a new token through R and rdrop2.

Now, whenever I generate a new token I get a short-lived token (prefix sl.) They expire in 4 hours.

I need the token to be long lived (not expire).

This article says long lived tokens were retired in Sep 2021 - but I created mine in October.

Is there still a way to create long lived tokens?
