Unwanted pop - ups

See the article https://support.apple.com/en-in/guide/safari/ibrwe2159f50/mac

open the url bar use deny location and exactly the same block and notify for pop up windows , in your screen shot click on don't allow .

In safari preferences > websites , under locations select the web site and click on remove button .

Also in pop up windows first remove it and block as per screen shot .

In notifications , remove it and see the screen shot settings .

Click the Safari menu and select Preferences... > Websites > Location.

A list of currently open websites will appear. Select the one for that website, and change it to your preference.

I understand that message appears repeatedly, implying it appears and then it disappears.

How have you been getting rid of it?
