App Platfrom - Laravel Application Caching

I have tried a few tutorials and ways to implement caching in my Laravel application by adding middlewares, editing .htaccess, modifing headers and so on. Sadly nothing seems to work and I can’t find a way to configure the server on the App Platform to cache my images and everything else with Cloudflare.

My Cache-Control header is Private in every image request

Accept-Ranges:
bytes

Alt-Svc:
h3=":443"; ma=86400

Cache-Control:
private

Cf-Cache-Status:
BYPASS

Cf-Ray:
