The single longitudinal target-spin asymmetry in exclusive dijet production is sensitive to the gluon OAM density. The latter contributes to the spin asymmetry with a characteristic azimuthal angular modulation of $\sin(\phi_{\Delta} - \phi_q)$, where $\phi_{\Delta}$ and $\phi_q$ are the azimuthal angles of the proton momentum transfer and the relative transverse momentum between the quark-antiquark pair. This study will motivate a first measurement of the gluon OAM at the Electron-Ion Collider.
