Not there you are correct it was there but checked and kinda remember removing it in 18.04 not sure why at this point. Have it back from this post:

Thank you for information. 
Edit:
Just looked closer and had added it back to Accessories after finding post and now looking closer it is also in Graphics. Delete in Graphics and it deletes the one in Accessories. Tried a couple of more times with same result. Think that was reason for getting rid of it in first place. Yes could just uncheck it in Graphics but mind says no. Just going to leave out as no way going to waste any time troubleshooting as have it as a bookmark anyway.
