I’ve found that any remaining trapped air that just won’t move upon bleeding the brakes will eventually move upon riding the bike and repeatedly braking. I had a gravel build with some very stubborn calipers that I could not get the rear brake properly bled on whatever I tried. One ride across bumpy terrain and all the air was rattled free and it moved up to the lever so I only had to quickly rebleed it and done.

Try putting the mineral oil funnel attached to the top of the shifter and pump the brake lever to get rid of any remaining trapped air. If no more bubbles come out, remove the funnel and seal it. Double check there isn't a leak either by the calipers or the levers. Then pump the brake lever again for as many times as possible until you feel the calipers engaging.

Honestly I find Shimano hydraulic brakes much easier to setup.
