Sensitive user name revealed in log in to sites

When I am logging into my bank’s webisite on my Huwawei P30 android phone it asks for my user name. This is then displayed in a box. I want to turn off this feature on certain sensitive sites. Can I do this or is it a global setting? I cannot find anything. Note, it is NOT autocomplete

Actual Result (gifs and screenshots are welcome!): see screenshot

Expected result: empty suggestion box on this site

Reproduces how often: always

Operating System and Brave Version(See the About Brave page in the main menu): Android

Go into the password manager, search oxbury and you can delete the username or the whole entry completely.
