…trap (#762) ## Description Accounts bootstrapped with `--trust` or `--trust-for-lookup` need `sts:TagSession` permissions in AssumeRolePolicy. I got errors during `cdk deploy` run in CD pipelines executed on EKS cluster on the trusted account. Error message: Could not assume role in target account using current credentials (which are for account `<TRUSTED_ACCOUT>`) User: `arn:aws:sts::<TRUSTED_ACCOUT>:assumed-role/<eks-pod-role>` is not authorized to perform: `sts:TagSession` on resource: `arn:aws:iam::<TARGET_ACCOUNT>:role/cdk-hnb659fds-lookup-role-<TARGET_ACCOUNT>-us-east-1` Troubleshooting revealed that DeploymentActionRole, FilePublishingRole, ImagePublishingRole, LookupRole don't have `sts:TagSession`. After updating AssumeRolePolicy `cdk deploy` worked normally. Fixes aws/aws-cdk#31557 --- By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license
