4. trigger the push-based replicate, and verify the following on the destination registry:
5. please check the SBOM column displays Not Generated. Should this be SBOM details with a hyper link?
6. please check that the DOWNLOAD SBOM button/link doesn't work. (it does not download a sbom file to the local machine)
