Should we also post prod deploys in #expensify-open-source?

Hi @luacmartins, I'm unsure how to test this without causing havoc with the current release. Should we merge and use internal testing to verify against the next official release and CP?

Updated! Added the step to post prod deploys to #expensify-open-source.

@Julesssss I think that might be the only way.

Could do with some more emoji

[roryabraham]

LGTM, but I agree with @Julesssss that it's lacking in emoji.

Live-testing changes like this always requires some patience and persistence. You don't necessarily have follow the testing instructions to the T in order to verify it works, just remember to verify it when CPs / staging deploys / prod deploys happen.

Good points, will keep an eye out for this. Merging now.

✋ This PR was not deployed to staging yet because QA is ongoing. It will be automatically deployed to staging after the next production release.
