❔ how to tell if a TCP request is a HTTP request

I am making a little proof of concept for a service that listens to TCP port
when it receives a request it returns the same text as an answer for now
I can also send request via a browser and I receive it but i need to apply special header and stuff to reply to HTTP request

When a request is sent from browser it looks like this:
GET /OMEGALUL HTTP/1.1
HOST: LOCALHOST:13000
CONNECTION: KEEP-ALIVE
CACHE-CONTROL: MAX-AGE=0
SEC-CH-UA: "GOOGLE CHROME";V="111", "NOT(A:BRAND";V="8", "CHROMIUM";V="111"
SEC-CH-UA-MOBILE: ?0
SEC-CH-UA-PLATFORM: "WINDOWS"

SEC-FETCH-DEST: DOCUMENT

is it safe to say that if request contains "HTTP/1.1" it is a http request and should be answered differently?
