Work From Home was absolutely massive worldwide especially on streaming (most viewed video released this year) and is the biggest single by a girl group this decade.
WFH has just more views on YT. Work sold more, it peaked higher in airplay, it has more streams on Spotify/AM, it went #1 in more countries and it stayed 9 weeks at the top of the Hot 100.
OT: Work outpeaked & outsold WFH, broke the records for most days at #1 on Spotify, the video has nearly 470M views despite being age restricted for a few days, and it's certified Platinum in 10 countries (vs WFH in 9 countries), so Work.
