Azure AD SAML integration Settings for key exchange missing

I am trying to do Azure AD SAML integration, having the below exception, could you please let me know if the exchange key is embedded in the metadata URL or where can I find it in Azure AD?

java.lang.Exception: Settings for key exchange missing. Please specify at least the option exchange_key with a shared secret.

Hi @vikasgurlinka

Could you share your config.yml file?
