Yes, you must display the consent screen. Bright Data believes in total transparency, and that users should always decide if they want to opt-in. The Bright SDK will not work if your code does not display the consent screen.
You cannot modify the consent screen’s main texts, layout or graphics, but you are able to specify specific items (e.g. the name of your app, text to display on the buttons etc). Check out the SDK documentation for specifics.
