MicrosoftGood luck finding it, but this is the minimum required version (per UserVoice):
"I’m excited to announce that the new Large Gallery view, allowing users to see up to 49 participant in a meeting, has started rolling out! Large Gallery will release as an optional (preview) feature that can be turned on at any time during a meeting, and will be available in desktop Teams client on both Windows & Mac in version 19173 or later."
MS makes getting on the true latest version of Teams almost impossible. Many are marooned on ones from a month or two ago (check for updates says there are no updates available). Even a direct download from the site(!) doesn't yield 19173 or later (and there is at least one later one: 19565).
