How to make phone number clickable?

Hello elementor Tech Support,

I am totally new to Elementor Page Builder. I am using your Elementor Pro through a purchased theme on Themeforest. I have 3 questions

1. How to make Top Header phone number and email clickable?

2. How to make Top Header Phone number and email show up on mobile device?

3. How to make phone number in the pages clickable?

I am not a IT pro, I have tried what I knew and searched online, but they didn’t work at all.

You can see phone number and Email on the top header, they are not clickable and they disappear on mobile devices. On the contact page, the phone number is not clickable.

Thank you
