And while we applaud your distinctive spirit, please 
begin your commit message with one of the following options 
(so it will show up in CHANGELOG.md):

- feat (new feature)
- fix (bug fix)
- docs (changes to documentation)
- style (formatting, missing semicolons, etc; no code change)
- refactor (refactoring production code)
- test (adding missing tests, refactoring tests; no production code change)
- chore

ie. 
	feat(sfu switch): Add ability to switch between p2p and sfu modes
	chore(bump dependency): Update sentry
	refactor(embedUtil): Rename maybeStartCamera to callMeMaybeStartCamera
