I know; I have read; but I have tested myselft.That's odd, because of Hagazi's own github site it says "Brave (aggressive mode only),"
Even in normal mode of Brave shields, adding hagezi pro list prevents scripts from loading which initiate pop up blockers.
Also adding hagezi pro dns in Brave settings do the trick.
Without both, Brave shields with all built-in lists enabled and on aggressive mode fails to stop those scripts; only AG and uBOL can stop them without the help of hagezi.
