Is it possible to add search engines with query parameters (in Vanadium, or any other Chromium based Android browser)? For example, I want Mullvad Leta to default to Brave when searching, so would need to add the engine to the query:
https://leta.mullvad.net/?q=%s&engine=brave
but when I make a search, only the following is kept:
https://leta.mullvad.net/?q=%s

I did not see anything on the forum, Github, or elsewhere about this, so thanks in advance!

Chromite uses chrome://settings/searchEngines to add custom search engines, but that does not seem to be available in Vanadium.
