Error after command at+qcfg="dbgctl"

I was attempting to debug the RM500Q-GL using QWinLog, but I encountered an issue. According to this forum post, it’s necessary to enable debug mode first. However, when I try to execute the command AT+QCFG="DBGCTL", 0, I receive an error. Additionally, the DBGCTL option does not appear when I run AT+QCFG=?.

Could you please assist me in resolving this issue or suggest an alternative method to enable debugging?
