What is true of it
Bm6 is B, D, F♯ and G♯ — 1, b3, 5 and 6 counted from B.
These are also the notes of G♯m7♭5/B and A♭m7♭5/B. 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 5 fingerings below is x20102: 3 fingers, held at the 1st fret.
2 of them use open strings, which is what makes a shape quiet to change to.
1 string stays silent.
Where its notes are on the neck
The brass dots are B, 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.
