Removing an Old Vsti ( monologue) from a track

Ive opened an old project which used to contain monologue but im trying to delete it or remove the track from the project page and mixed . If you right click there’s no way to remove the old VSti or nothing in the inspector to remove it , i know you can just hide it but i want to totally remove it so when im opening the project im not getting the missing instrument box coming up .
