@Keerthi421 thanks for the PR. Waiting for this to be merged soon :) 👍
Notifications without sound are not very helpful.

apologies if that wasn't obvious but i was waiting for the CI issues to be resolved before i'd properly review the changes.

p.s. we use changefiles (example) and don't modify the changelog manually.

Hey! What's the correct way to bundle the sound file with the app? I've tried adding it as a resource and then using resolveResource to get the path, but no cigar (the default sound seems to play on MacOS). Thanks!
