sudo-prompt fails to detect pkexec or kdesudo in "strictly" confined snap

[Melvin-Abraham]

I am making an electron app which I am distributing as a "strictly" confined snap application. This app requires superuser privileges to run some commands, so I am using sudo-prompt. But it turns out that the command fails as it fails to find pkexec or kdesudo for authentication purpose. This does work in a "classic" snap though. Is there any way to get it working in a strictly confined snap?

Code Snippet

sudo.exec('snap refresh g-assist', {name: 'Google Assistant'}, (err, stdout, stderr) => {
    if (err) console.log(err);
    ...
});

Error Stacktrace

Error: Unable to find pkexec or kdesudo.
