Proxmox gemu agent file-read how?

Question

Proxmox

There is also a PVE/API2/Qemu.pm file which contains a list of allowed commands in the $guest_agent_commands variable. But adding the necessary functions there does not solve the problem. In addition, it is not clear how to pass parameters (
Proxmox 4.4
guest Windows (XP-W10).
