restoring redshift serverless from provisioned cluster snapshot

I recently enabled redshift serverless endpoint, and to benchmark it I want to restore it from a snapshot of a legacy provisioned cluster, so we have identical data sets to start with. However, when I select to restore the snapshot to the serverless (using console as described in https://docs.aws.amazon.com/redshift/latest/mgmt/serverless-snapshots-recovery.html, and confirming that it will replace all my serverless databases), nothing seems to happen (no error, but also the serverless databases are not replaced with the snapshot).

I already tried adding redshift full access policy to the IAM role of the serverless endpoint, but that didn't help.

Has anyone already achieved this?
