We have looked at the documentation regarding .acs files https://pro.arcgis.com/en/pro-app/latest/help/projects/connect-to-cloud-stores.htm for access to AWS S3 via ArcPro.
But unfortunately we do not support long-lived AWS access keys as required in the documentation
Is there a way of creating a dynamic/or token based access using SSO and AcrPro?
Many thanks
