You could do a custom action from your character sheet. Click “Manage Custom” from the actions tab. Make it a ranged weapon attack. Set the die type and die count, range, stat it uses etc. make sure you check off proficient and display as attack. It will show up on your sheet a little further down from the Attack window.
