What is true of it
Gm7 is G, B♭, D and F — 1, b3, 5 and b7 counted from G.
These are also the notes of B♭6/G and A♯6/G. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
On an instrument that cannot reach all 4, the 5 goes first, in that order.
The easiest of the 2 fingerings below is 0211: 3 fingers, held at the 1st fret.
1 of them use open strings, which is what makes a shape quiet to change to.
Where its notes are on the neck
The brass dots are G, the root. Everything else is a chord tone with its degree printed in it.

aaaa
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.
