How do i validate my entra token in my springboot app?

i wanted to do the signature validation and kid after fetching it i am doing it something like :
String uri = "https://login.microsoftonline.com/"+tokenConfig.getTenantId()+"/discovery/v2.0/keys";

        Jwk jwk = fetchJwks(uri,kid);

        Claims genClaims =  Jwts.parserBuilder()

                .setSigningKey(jwk.getPublicKey())

                .requireIssuer(tokenConfig.getIssuer())

                .requireAudience(tokenConfig.getAudience())

                .build()

                .parseClaimsJws(token)

                .getBody();

its failing in claims how do i approach from here. i says "JWT signature does not match locally computed signature. JWT validity cannot be asserted and should not be trusted" t
