 It follows from the lemma that we can construct an isomorphism

 We must now show that the isomorphism does not depend on this choice.

 The first movie move is to push $E$ across an $n$-ball $B$ as above, then push it back.
 The result is equivalent to doing nothing.

 But if $n=1$, then we are in the case of ordinary algebroids and bimodules,
 and this is just the well-known ``Frobenius reciprocity" result for bimodules \cite{MR1424954}.
