Click Launch APM failed

Kibana 8.5.2:

Elasticsearch 8.5.2:

APM Server 8.6.0:

APM Agent 5.x @elastic/apm-rum-angular:

After checked successfully APM Server and APM agent status, and clicked on Launch APM button in Observability/APM page.

I don't know why but I always redirected on this page.

What am I missing in the kibana side configuration to display observability of a web application?
