debug gem

I see that RubyMine's debugger works with the debug gem according to docs. But when I try to add a Ruby remote debug configuration, it defaults to showing the ruby-debug-ide gem command. Does RubyMine work without the ruby-debug-ide gem? Is there a way to enable increased logging so I can troubleshoot attaching to the debugger? I can confirm that the remote debugger is enabled on the server side and I can connect to it via TCP/IP and it works with VSCode and the rdbg extension.
