I was in a really important meeting in Montreal a couple years ago - I had a 2019 MBP and my colleague had an older one with an HDMI port.HDMI doesn’t always work - depends on the system those presenters have installed - trust me!
His actually zinged the whole system and we couldn't get his computer to present.
I ran everything from mine with a USB-C to HDMI dongle. Wasn't a problem.
(otherwise in our corp offices we use Zoom Conference Rooms and now Teams... or AirPlay)
