Commands to exit from EDL mode

Hello all. I have a G7 thinq, the power button of my phone is not working, so I cannot boot into EDL mode. I saw commands to enter into EDL mode but nothing regarding exiting from it and rebooting back to home. Could anyone help?
Not sure if there is any other way. I've tried once to try booting to EDL using commands which did not work. And also the only method I know of to exit EDL is to hold the power + volume - button.
Both the Python EDL client (edl.py reset) and my own Windows EDL client (edl.exe /z) have operations to reboot from EDL mode.
