When you add a webpage, click on profile and then “Manage Profiles”
Onece there add a new profile and click “open remote browser”. A browser window opens and usually accesses google.com. You can then enter your desired URL, it will open and the cookie banner will appear. You can then make the choice you want to (though it may be best to allow cookies so the setting gets saved) and click on “Save Cookies and Close” in the upper right corner. You can then exit th profiles section.
Now when you access the website in you can select the profile you created. When accessing the website it will provide access to the cookies previously created and thus the cookie banner won’t appear.
This may not last forever, as cookies expire. In that case you need to repeat the first steps and resave the cookie.
