Attach to Process does not show all processes on Mac

When running "dotnet run" from the command line, the "run" command launches a child process that is the actual application (a dotnet core 3.1 website in this case) that is running, but it does not show up in the list of processes available for attaching to.
However, that child process is the process that needs to be attched to in order to debug it. I confirmed this using VSCode's attach to debugger.

Whenever I bring up the "Attach to Process" dialog, it only shows "dotnet" processes.

Example: With a asp.net project named ProjectA, the "dotnet run" command will show up in the process list _and_ it will have a child process named "ProjectA" but the child does not appear in Rider to attach to.

Am I missing something on how to show all processes, or to be able to attach directly to a PID that I know?
