Trying to safely kill processes doesn't work if spawed with Niri

[scientiac]

If I launch a program, e.g. Firefox from the terminal and use pkill firefox from the terminal, it kills the process.
But, If I launch the program firefox from wofi or rofi or fuzzel or niri msg action spawn -- firefox or using a keybind, pkill cannot kill the program.

pkill or kill <pid> both doesn't work except for kill -9 which I am currently using in my config.
