Prevent Lock Screen

I just started using Sleep as Android on my Pixel 8. When I start sleep tracking, it initially shows a screen with stats and the audio sensing line, and after a short time switches to a dark screen with a dim clock, which is all good. The problem is that after 2 minutes, my lock screen takes over, which is black, but the text is brighter, and the clock is smaller, which I don’t like. The “White Noise” app that I was using could take over the screen and keep it’s moving clock on all night without issue, can that be done with Sleep as Android? Note my phone is on a dock, so power use is not a concern.
