Authorize application using SDK

[rrrnld]

I have created an app in the Saleor dashboard and I'd like to implement it in Typescript using the @saleor/sdk. How can I set it up to use the auth token? I know on a deeper level I just have to convince the client to set an http header Authorization: JWT … but I have no clue how to do that using your provided SDK.

Any help is very appreciated!

PS: Note that this is an app without a GUI. It is meant to react to incoming events on Webhooks and manage Saleor accordingly via its API.
