Why running docker-compose on ubuntu I got Permission denied error?

I have installed fresh kubuntu 22.04 on my laptop and when I try to install docker
I have installed docker-ce and docker-compose :

Description: Docker: the open-source application container engine
Docker is a product for you to build, ship and run any application as a
lightweight container
.
Docker containers are both hardware-agnostic and platform-agnostic. This means
they can run anywhere, from your laptop to the largest cloud compute instance and
everything in between - and they don't require you to use a particular
language, framework or packaging system. That makes them great building blocks
for deploying and scaling web apps, databases, and backend services without
depending on a particular stack or provider.

I have run command :

sudo chmod +x /usr/bin/docker-compose

without errors.
But running docker on my project I got “Permission denied” error anyway

serge@serge-at-home:/_wwwroot/lar/FilamentBanners/__DOCKER$ docker-compose up -d --build

What did I miss during installation ?
