Outlook and Gmail integration issues

Up until now, I’ve been using Outlook to handle all my Gmail stuff because—let's be honest—it's way more user-friendly than just sticking to the Gmail interface. But for the last few days, Outlook has been flat-out refusing to let me log in. Is there any way I can fix this myself?
It keeps throwing this error at me:
AUTHENTICATIONFAILED] Invalid credentials (Failure)

Here’s the setup:
Account: xxxxxx
Server: imap.gmail.com
Username: xxxxxxx@gmail.com
Protocol: IMAP
Port: 993
Secure (SSL): 1
Code: 800cccd1

So, it’s just not an option anymore? If I actually managed to wrap my head around what they're saying here...

Look, if you haven't turned on 2FA, you can just stick with the "Less secure app" option. But if you actually have it enabled, then you'll need to go through with App passwords.

The "less secure apps" option is gone; it’s just app passwords now. I just wonder if that'll actually work on this ancient version of Outlook
