how to capacitor with https://capacitorjs.com/docs/apis/preferences used ?

Hi <@906542533272805417> 

Not sure what your question is

When the application closes on the phone, the token information goes away. It needs to be changed to work with permanent storage.

I think you should get in touch and work on writing a plug-in for the capacitor.

As a sponsor, you can support plugin writing.

If you succeed in this, you will have a large audience behind you. 🔥

In the meantime one way would be to switch to using localstorage to store the tokens which can then use the preferences API for storage too

This example app might be a good reference point: https://github.com/supertokens/supertokens-auth-react/tree/master/examples/with-localstorage
