Service entries in Anthos Service Mesh

问题

For some test, I have created a ServiceEntry in Anthos Service Mesh. It also works when accessing that service with a curl pod, the headers are set correctly

curl -v postman-echo.com/get

However, that service entry does not appear neither in the dash board nor in access logs. It seems that dashboard is limited to kubernetes services. If this is the case, is this only a limitation of the ASM dashboard (and maybe available in other installations, for example open source Istio with Kiali) or a fundamental limitation? Or am I doing something wrong?
