Thanks!

Q: why have access token be a param, and not depend solely on await retrieveTokens()? More efficient if you have the access token at hand already? (Practically, retrieveTokens() will be near instant)

[ottokruse]

To fix prettier issues, run this in the root of the workspace:

npx prettier -w .

The reason is that we are using this lib server side on svelte. We wanted to use cookies and it became a bit difficult to set and get those cookies.

So we wanted to pass the token as a param instead.

Got it, understood, and thanks for the explanation.

Cool to hear you use this in Svelte on server side! Let us know any feedback you have to make life easier for that (such as more docs maybe ...)

See prettier is still failing. Make sure you have the exact same version as the lib? Should be 3.1.1
