Hey, I'm getting {\“error\“:\“unsupported_grant_type\“}” and I've checked everything millions of times and everything is correct. I'm getting credentials.authorizationCode and passing it to server - which makes a request: [{"iss"=>"teamId", "iat"=>1566222397, "exp"=>1581774397, "aud"=>"https://appleid.apple.com", "sub"=>"com.example.MyApp"}, {"typ"=>"JWT", "alg"=>"ES256", "kid"=>"keyId"}] iss, sub and kid container real values of course.

{:client_id=>"com.example.MyApp",
:client_secret=>"secret",
:grant_type=>"authorization_code"}

Everything looks just as the example above and I'm keep getting an error. Any ideas?
