correct command in cmd

[moein24]

Hi
I have been using the below command in cmd, and it want an argument for flag part.

telegram-desktop-decrypt_windows_amd64.exe decrypt C:\Users\sgr\AppData\Roaming\Telegram Desktop\tdata\D877F783D5D3EF8C F100C0A2FB11645As --stream

\
Err: flag needs an argument: --stream
Usage:
telegram-desktop-decrypt_windows_amd64.exe decrypt [tdata file] [key in hex (only first 136 bytes matter)] [flags]

Flags:
-h, --help help for decrypt
-s, --stream int stream number (default=0)
\\

i dont know how to find the right argument for flag
