Help to migrate blichess to Capacitor 6

[vovagorodok]

In order to release blichess on Google Play, upgrade to Capacitor 6 (SDK 34) is needed.
The release in Google Play is needed so that as many people as possible can test the new protocol before adding it to other applications.
It was decided to write here because there is a greater chance to find a hint

Ported version compiles and works fine:
vovagorodok/blichess@bluetooth...vovagorodok:blichess:migrate-to-capacitor-6
Except one error. After migration, application can't connect to lichess.org, because of log:
File: https://localhost/ - Line 0 - Msg: Access to fetch at 'https://lichess.org/' from origin 'https://localhost' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I wonder what happened that Capacitor 6 now requires CORS from https://localhost/
