Monodromy-isometry equality for O'Grady's ten-dimensional example

Let $X$ be an irreducible holomorphic symplectic manifold deformation equivalent to O'Grady's $10$-dimensional exceptional example. Monodromy-isometry conjecture. $Mon^2(X)=O^+[H^2(X,\mathbb Z)]$. This asserts that every signed orientation-preserving isometry of the second cohomology lattice is realized by monodromy; the source does not specify whether the assertion has been resolved.
