Can't find action overflow

I'm working on an older pixel 3 xl, with Android 11. I've been referencing Android for Dummies. On the chapter for web browsing (page 119) I've noticed there's a diagram for a Google page. Problem is, my phone doesn't the action overflow icon (and Tabs). This is driving me crazy. Is there something I'm missing, because without it I can't do much. Thanks.

 

I call it action overflow because that's what the book calls it. I think the idea for that name is that the icon gets you things that won't fit in the regular icon area.

There's no little square icon. It's like some things are just missing. I assumed that would be something under settings, but no.

I'd prefer to use Chrome, because I'm (usually) familiar with it, like on my desktop.

 

Thank you. But I don't always get the three dots, which is the problem. Just now I did when playing around, but I don't always get them. I'm not sure what I'm doing wrong with that.

 

What worked for me was to download the beta version for Chrome. No problems now, though I did waste hours. Thx all.
