SUSE Rancher setup permission issue

We have setup SUSE Rancher via AWS Marketplace. We have tried both versions available v20230606 or v20230503. With both versions we have the same permissions issue during the Rancher Setup wizard. IAM permission and role are OK.
One thing I have to mention is that we are using AWS multiple accounts setup and external IdP.
We have tested on single AWS account and it works fine.
Can you help us on this issue?

For more complex setups, we recommend doing a manual deployment of Rancher, per the docs.

Just noticing this Enis. Did you find resolution? While ‘Rancher Setup’ is designed to deploy into a single AWS IAM account, there should be no issue connecting to manage cluster API addresses across multiple accounts using key based or other authentication. Curious if you got over the hurdle.
