What is true of it

G♭m9 is G♭, B♭♭, D♭, F♭ and A♭ — 1, b3, 5, b7 and 9 counted from G♭.

B♭♭ is a double flat, and it has to be: every letter from G♭ upwards is used once, so the b3 cannot be written any other way.

On an instrument that cannot reach all 5, the 5 and 1 go first, in that order.

The easiest of the 5 fingerings below is 202120: 4 fingers, held at the 1st fret.

1 of them use open strings, which is what makes a shape quiet to change to.

1 of the 5 need a barre.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
