Brave setting to defeat second Facebook pop-up


Description of the issue:

I recently switched from Firefox(w/ Ad Block) to Brave which is now synced to my three devices.

Although I do not log in or have a Facebook account, I do like to occasionally look into some FB Community sites which are open to all. When using Firefox, the FB Community site comes up and the sign-in pop-up can be canceled via the ‘X’. I then proceed to look at these sites for an indefinite time.

When using Brave or Chrome on these same FB sites, the initial pop-up can be canceled but a second pop-up appears within 15 or 20 seconds that CANNOT be canceled which renders the sites unviewable.

Is there a setting that can be changed in Brave (or Chrome) which would disable this second FB pop-up?
How can this issue be reproduced?

Expected result: No second pop-up.

Brave Version( check About Brave): 1.69.160
