How to work only on file links and ignore links to headings and blocks in files

[jiajiala]

As shown in the figure, both the link to the file and the link to the subtitle in it will now trigger the avatar display
Expect the avatar display to trigger only when linking to the entire file
Is that possible? Thank you

.data-link-icon[data-link-Kr_js*="001"]::before{content: url(http://……001.jpg);}
div[data-id="1"] div.setting-item-description,
[data-link-Kr_js="001" i]
{
color: #c9c9c9;;
}
This is my css

I wonder how I can make this icon appear only on links to files and ignore links to subcontent
