Add Brave search as default

[anarchotaoist]

I am trying to add Brave search as the default search engine in the Android Ghostery browser.
I have copied and pasted in the search string from Brave search information:
https://search.brave.com/search?q=%s
but I get
"Error connecting to "Brave Search""

How can I set Brave Search as default?

Ghostery Browser version: 1.0.2.033
on Oneplus 8T running 'LineageOS for Microg' 18 (Android 10)
