Possible leftover from old API

[yyxcv]

In commit da33d81 the function 'exchangeAuthorizationCode' was deleted from /frontend/src/api.js

The function is still used in 'LoginRedirectBranch.tsx' (see Screenshot) .
Can it and the component 'ExchangeAuthCode' be safely removed from it?

As @opatut's commit you mention was back in 2021 during the shift to the python backend (and keycloak as auth backend) it's likely a leftover from the old homebrew auth backend and can safely be removed.
