Uploading Keystore and SP Metadata XML to auth0


I am trying to add a SAML authentification to my OutSystems program. The login via auth0 works just fine, but after that, the response is “UNABLE TO PROCESS REQUEST Error processing SAML response”. OutSystems indicates that I need to upload the above-mentioned files to auth0 so that OutSystems can decrypt the message from auth0. Is there an option to do so? Any help is much appreciated because I need this for my Bachelor thesis.
