Gadget to achieve Built For Shopify issues

We used gadget to make our App, Moby Marketing on Shopify,, and now trying to qualify for Built for shopify but some requirements are way off. the app is quite simple and for sales, so no big image loads etc but - 1) our LCP (largest contentful Paint ) was 8 secs for our shopify app even for loading an empty page, no help on discord. Then via other communities and hacks we got it down to 3.5 sec, which is still is higher than required by shopify. How can we not get a simple resolve if gadget is approved for shopify app coding ? 2) CLS is also border line, rest all well within. Any help to achieve BFS status please connect.
