How to change SSH port number

Using VPS with Ubuntu latest and new to linux command. Its for hosting a website.

Tried via sudo nano /etc/ssh/sshd_config does not seem to work.

Tried ports like 2864 ,31457 but nope :( The default port just does NOT change.

Also, when I went to change the port number it was written port and listenaddress is not used when sshd is socket activated. screenshot: https://imgur.com/b2t1ASm

Anyone can help with the proper command?
