In {FMR25}, Fantechi--Miró-Roig show how to construct new Lagrangian subspaces of the moduli of simple perfect sheaves on a K3 surface from a given one. We reinterpret their construction using the tools and flexibility of derived algebraic geometry. This allows us to generalize from K3 surfaces to (possibly singular) Calabi--Yau schemes of arbitrary dimensions.
