Thanks for sharing this feedback. The idea description does not indicate where this text is displaying, but it sounds like it needs to be addressed by your school's local Canvas admin. Would you please contact them directly to discuss this?
Actually Kaltura is listed alphabetically in the ADD external tool options. However, it is listed as "Embed Kaltura". Now that I've played around more with Canvas I can find it easier, but why not name is "Kaltura - Embed" so the "K" comes before the "E". That should be an easy fix.
