Alternatively, join my meetings on time. You click End Call, then Join. It takes 3 seconds.
You get Outlook reminders 15 minutes in advance. Webex/Teams notifications 5 minutes in advance. I’m sure you can make your watch vibrate or something.
People at my office join every meeting 5 minutes late because no one expects meetings to start on time anymore. So I guess we’re following this advice in all but the nominally scheduled time. Drives me nuts.
I'm absolutely baffled by colleague who somehow manage to be five minutes late to an online meeting while working from home. Because you're right, you get a reminder 10 - 15 minutes in advance, you just need to click the join meeting button, you're already at the computer. We have, for remote meetings, a five minute buffer at the start of every meeting, for people to "settle in" makes no sense, just start the meeting.
In general a lot of people just aren't being serious about meetings, which I guess is also why many hate them. So key indicators of a bad meeting is: runs more than 60 minutes, no meeting plan, documents or talking points provided in advance, more than five people (unless the meeting is more of a briefing).
