uploadCrossSigningSignatures method

Future<Map<String, Map<String, Map<String, Object?>>>?> uploadCrossSigningSignatures(Map<String, Map<String, Map<String, Object?>>> signatures)

Publishes cross-signing signatures for the user. The request body is a map from user ID to key ID to signed JSON object.

signatures The signatures to be published.

returns failures: A map from user ID to key ID to an error for any signatures that failed. If a signature was invalid, the errcode will be set to M_INVALID_SIGNATURE.
