How can I solve this error: Property 'refresh_token' does not exist on type 'object'?

Hello,

I am trying to make a replica in Typescript of the Dropbox webhook (that converts md files to html) that was built in Python. I copy-pasted the authentication flow from this example and I had to change a few things along the way till I reached this error that I couldn't solve.

Here is a screenshot:

The documentation of the SDK are quite poor they didn't help at all.

Thanks in advance.

I have made it! Here is my repo: https://github.com/adnanlah/dropbox-mdwebhook-ts, a typescript clone of the Markdown to HTML webhook that was made with Flask. Thanks to @Greg-DB, @Здравко, and @Brogers for the immense help ♥
