Update.exe parameters changed as of Firefox version 128.10.X

Hello, I use a Powershell script to manually install a Firefox update. Starting with version 128.10.xx and higher, Update.exe expects different parameters, but I'm not sure what the parameter names mean (see screenshot). Can someone explain to me what I need to pass for “arg-version” and “wich-invocation”? All other parameters were already present in the previous version of Update.exe, and I understand those, but unfortunately I don't know exactly what I need to pass for these two. Thank you very much in advance for any help.
