How do I close all, or many at once, Chrome tabs on Android on a phone?

I'm on Google Pixel 2, Android 11, Chrome 87.0.4280.101.

I have 494 open tabs, as I explain in my answer here on how to count them. I need to selectively close about 450 of them, or just close all of them then re-open about 20 to 50 of them.

How do I mass-close many or all of them at once?

The last time I mass-closed hundreds of tabs manually I sat there for like 30 minutes swiping until they were all closed. I don't want to do that again. That was ridiculous. (Compared to full computers, phones are garbage. :))

This tablet-specific answer doesn't seem to apply to phones, or to apply anymore to the latest versions, so it does not contain an answer that works for me: How do I close all tabs in Chrome for Android?.

Here's what I see in my Chrome menu when I click on the 3 dots in the top-right corner:
