How to Make a Button Redirect to Employer Website Using URL from Custom Field?

I’m working on a WordPress project where I need a button to redirect users directly to an employer’s website. The URL for the website is stored in a custom field called employer-website.

Here’s the scenario:

The custom field employer-website contains the URL of the employer’s website.
I want a button on the employer’s profile page that, when clicked, takes the user to the URL specified in the employer-website custom field.
How can I achieve this functionality in WordPress?

Any help or guidance on how to implement this would be greatly appreciated. Thank you!
