Limitation in chord entry

When I enter G2 nothing appears.

Type “Gsus2” with the following selected in Engraving Options/Chords for “Appearance of suspended second:”

I select engraving and see three options: format music frames, format systems and bracketing.
No idea how to get there this is.
Sorry. newbie.
