Grafana authentication with AWS Cognito

Hi,

running Grafana 8.3.0. Can anybody point us to some instructions to setup Grafana authentication with AWS Cognito.

Tried the following with no success:
https://community.grafana.com/t/how-to-integrate-grafana-with-cognito/7026/2
https://stackoverflow.com/questions/56038548/aws-cognito-grafana-login-oauthloginmissing-saved-state-and-cant-login-as
etc… (links limited to 2)

Continue to get: An error was encountered with the requested page after multiple changes of AWS Cognito and grafana.ini.

Can anybody help?

Cheers,
Andrea
