Need help Removing Ultimat Guitar Installer Icon On My Pixel 2, Cannot Remove

[Android Central Question]

An icon for Ultimate Guitar Tabs showed up on my Pixel 2 today after I clicked on a link in my news feed. It looks just like an app, but if I hold my finger on it, I see a menu that says"App Info"and "Install" (rather than "Uninstall"). If I click on the icon, it opens up what look like an app, but there's an istall button on it/ It does not show up in Settings/Apps & Notifications, and Malwarebytes does not see it. If I try to drag it to the top of the screen to remove it, it does not remove. There is no option to uninstall. I've searched high and low, but can't find any info about this online. Definitely some voodoo going on here. Any help would be appreciated.
