WHM PHP ZIP Extension

We need a freelance who is familiar with WHM and Envato theme installations. We are trying to install themes to our sites and keep getting errors that there was an issue installing the template kit. PHP zip extension not loaded. We would like to share a screen and you guide me through adding to server or 2 sites. Confused if this needs to be done to each site or the server. Note we would like to share a screen and you direct us through the project. I have not been able to give root access in the past.

Also note that this only has for Envato Elementor Template Kit
Budget is for Micro Project
