To use LinkedIn button, you can only use the URL input, if URL input left empty it will use the current page URL. see https://github.com/MurhafSousli/ngx-sharebuttons/wiki/Meta-tags-inputs-compatibility

Regarding the meta tags, they are unified for most social media. I think LinkedIn uses the og:image and og:title

After publishing your site, you can test it out via LinkedIn Inspector https://www.linkedin.com/post-inspector/
