Stop snapshot from CLI other than ctrl C

Good Morning , I have been using kopia for my backup for windows and linux using kopia cli recently. on kopia UI I cansee an option of stop snapshot so it creates partial or incomplete snapshot , now I tried ctrl+C from cli its working , now I wanted to stop kopia programmatically . How can I do that anyone tried this please help me out here . Thank you

Send SIGINT signal to the process, see below example:

# Launch script
./ &
# Get its PID
# Terminates the program (like Ctrl+C)
kill -INT $PID
