Hyperlink showing/not showing

When using the Elementor canvas, hyperlinks are not underlined, when using default template they are.
Various solutions were explored including these proposed solutions

.elementor a,
.elementor a:visited {
      text-decoration: underline;	    
}

.entry-content a {
    text-decoration: underline;
}

.entry-content a {
    border-bottom: 1px solid #0a9e01;
}

Using a child theme.

Enter code in Additional CSS /Style.CSS
Neither added underline.

Then added following code.

.elementor a,
.elementor a:visited {
      text-decoration: underline;	    
}

.entry-content a {
    text-decoration: underline;
}

.entry-content a {
border-bottom: 1px solid #0a9e01;
}`

This added underline to all hyperlinks, menu and breadcrumbs, not what was wanted.
The answer came from Elementor support Andri .

This code works both in additional and style css.

.elementor .menu-item a, .elementor .elementor-widget-wp-widget-custom_html a {
    text-decoration: none;
    border-bottom: none;
}

Hope this helps any one who has a similar problem.
