Not able to change Kibana custom logo in 7.10

I am trying to customize the Kibana UI with custom message and logo, i tried following the guide published here - Custom Logo Kibana 7.10.0 (guide)
However, when run the npx command after making changes for login logo and text i get following error.

~# npx gzip-cli /usr/share/kibana/x-pack/plugins/security/target/public/security.chunk.4.js -e=gz -e=br
        npx: installed 16 in 3.921s

I'm able to gzip the js file with npx command, however, Kibana dashboard doesn't reflect the custom login message. I am assuming this could be due to version difference. Does anybody know which version of npm/npx is needed to gzip the file?

npm shouldn't be the difference here, it is gzip-cli. Can you try and install a newer version of that?
