ENTRYPOINT ["dotnet", "app"]

Container starts fine, but when I don't see any metrics in Elastic APM and if i go to profiler logs, there is nothing there:

/app # ls /profiler_logs/
/app # ls /elastic_apm_profiler/
__MACOSX                     elastic_apm_profiler_1.19.0
/app # ls /elastic_apm_profiler/elastic_apm_profiler_1.19.0/
LICENSE                     README                      integrations.yml            net461                      netstandard2.0
NOTICE                      elastic_apm_profiler.dll    libelastic_apm_profiler.so  netcoreapp3.1

Also I don't see libelastic_apm_profiler.so being loaded into the process:

/app # lsof -p 1 | grep libelastic
/app # 

Is something wrong with my Dockerfile setup? I know in documentation example there was plain Alpine image used. Do Microsoft Artifact Registry images require different handling?
