Optimizing Largest contentful paint score for embedded app

I have a shopify embedded app.

I am trying to optimize the embedded app’s Largest contentful paint score. Currently the LCP is 15s. However I am seeing lots of Shopify css and js files affecting the LCP.

My app dashboard contains only some divs with some reports (HTML) which I am loading through AJAX calls. I don’t have any images in the app dashboard.

Any pointers to reduce the LCP would be appreciated.
