PHP Imagick module : imagick module is not available with this php installation in ubuntu

I'm trying to install php-imagick to use with laravel intervention image package as its driver, I tried to install it via sudo apt-install php-imagick

php-imagick is already the newest version (3.4.3~rc2-2ubuntu4.1).
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.

I added extension=imagick.so to my php.ini file and tried restarting the php service with:

sudo service php7.3-fpm restart

But still getting the same message:

When I do php -m to see installed modules I get this error message:

PHP Warning:  PHP Startup: Unable to load dynamic library 'imagick.so' (tried: /usr/lib/php/20180731/imagick.so (/usr/lib/php/20180731/imagick.so: cannot open shared object file: No such file or directory), /usr/lib/php/20180731/imagick.so.so (/usr/lib/php/20180731/imagick.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

And when I do convert --version I get this message:
