host a php web app on aws amplify

I'm trying to build a laravel web app on aws amplify. I've configured an ECR with php, nodejs, npm, composer etc to handle laravel. I then use this image to build an aws amplify app. Although it deploys successfully it does not load php pages.

I can tell .htaccess is an issue because aws amplify doesn't appear to use it. Is there a way to convert .htaccess to amplify redirects/custom headers?

Is it even possible to run a laravel app on amplify?

Loading mysite.amplify.com/index.php only downloads the index.php file rather than loading.
