What is true of it

G♭m(maj7) is G♭, B♭♭, D♭ and F — 1, b3, 5 and 7 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 4, the 5 goes first, in that order.

The easiest of the 5 fingerings below is 20322x: 4 fingers, held at the 2nd fret.

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

3 of the 5 need a barre.

1 string stays silent.

The brass dots are G♭, the root. Everything else is a chord tone with its degree printed in it.

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.
