I want to implement the firebase app check backend implementation for Java/Springboot (Maven). The official documentation only provides for nodejs and python implementations but it provides steps for how to implement it in other custom backends (text). I tried to do it with auth0.JWT but did not success.
DecodedJWT x = JWT.decode(appCheckToken);
This did not give me decoded token and I want it to access some properties to validate algorithm etc as mentioned in the documentation.
