Deploying Codeigniter 4 Website on LAN server

I developed Codeigniter 4 website on my laptop running Mint Linux with LAMP.
I have another PC in the home network dedicated as an ubuntu 20.04 LTS server with LAMP installed.
On deploying the Codeigniter 4 website onto the Ubuntu server 20.04 LTS, and calling the ip address of it, i only get "index.php" displayed on the browser
How do i need to configure the Ubuntu server other than using virtual host configurations?
In the Mint Linux laptop, i can configure "httpd.conf" to point to the website, but in the 20.04 server, i only have "apache2.conf", and am not sure if and how to configure
Kindly help
