could you update the package.json, increasing the lower number by one, and com.github.IsmaelMartinez.teams_for_linux.appdata.xml with version details? Thanks again and apologies is taking longer to merge. Busy life!

Updated to 1.4.38.
So you are creating a release per commit?
Good to know for future PRs 😄.

Sometimes we do merge a few PRs together... but that is rare. Thanks for your contribution! I will release it as pre-release https://github.com/IsmaelMartinez/teams-for-linux/releases/tag/v1.4.38 for a couple of days. Thanks again!
