Is there a way to auto-start the auth flow for a specific provider in the react-ui based on e.g. a query parameter?

hey! yes there is. Checkout the custom UI docs section for thirdparty login. You can call those functions yourself if the query param is present and redirect the user to the auth provider without any user action

Does `supertokens-auth-react` have its own `getAuthorisationURLWithQueryParamsAndSetState` function?

I would like to avoid having to initialize both `supertokens-web-js`  ThirdPartyEmailPassword and instead only have to initialize `supertokens-auth-react`

the same import statement, except instead of web-js, put auth-react

I am implementing Okta login right now 😄
