The Kiali backstage plugin has several dependencies that should be kept up to date: 

• Backstage version: Maintained in the upstream repository https://github.com/backstage/community-plugins :
  • Backstage version upgrade
  • Dependencies upgrade requests
  • Feature request/Bug reports
  • Filter to check all of those requests: https://github.com/backstage/community-plugins/issues?q=is%3Aissue%20state%3Aopen%20kiali 
• Kiali API: If the kiali API is modified, it should be updated as well, to prevent errors in the ajax calls. 
• RHDH: Should be working in the RHDH as a dynamic plugin. It depends as well in RHDH version and OpenShift version (Ex. styles alignment). https://github.com/redhat-developer/rhdh-plugin-export-overlays
