Here is great tutorial about bracketing for panoramas

This could be a great technique even, if your not going for the pano shot and just want better detail. Although get the normal shot first, so at least you have something in case it doesn't work out.
Below is a link to some photos I shot on my Samsung S21 Ultra, to see if it works and it did. One shot was the normal point and shoot using the phones 1x lens. The stitched image was from 14 RAW photo (DNG) in Pro mode using the 3x lens. The compare image compares the two and an edited version in Lightroom
