Encrypted Mailto links [closed]

Sometimes when looking for a way to contact someone on the internet a javascript:linkTo_UnCryptMailto(XXXXXX); appears instead of the email address of that person.

When I click on it, the browser wants to open up an email program that is not configured and also not used, as I use web interfaces of a mail provider (such as gmail, yahoo, hotmail, protonmail and others.)

Is there any way to extract or find out the email address (name@something.com) so I can copy paste the address into the "to" box on the web interface?
