Hello,
I saw the screenshot you attached.
To change the name of the block you need to install and use the loco translate plugin and choose the correct path to translate the string.
You can also watch the video in our detailed documentation in the following link: https://www.youtube.com/watch?v=D3NsDdMzsls
If you want to change the icon then try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
.wd-my-account-links .downloads-link a:before {
content: “\f136”;
font-family: “woodmart-font”;
}
You can change the icon content and font-family according to your requirements.
And giving an external link is not possible.
Best Regards
