I create fields using relationships

BelongsTo::make

and want to add a search title image, the link to the image is stored as a url in the resource field

I tried making an img tag but the title escaped the html code

public function title()
{
    return "$this->name <img src='/open_emoji/lite_colored/$this->name.png'>";
}

https://nova.laravel.com/docs/4.0/resources/relationships.html#searchable-relations The documentation shows a picture to show that this is possible and that's it!

There is also a specific avatar field, but it's also poorly documented, and there's no explanation of how relationships are handled.

Can someone explain how to do this? I am using nova 4
