Current cosmological data show no statistically significant sign of an interaction between cold dark matter and dark energy, with LambdaCDM preferred, and future LSST and DESI data could constrain such a coupling at 20% precision.

abstract
Small distortions in the observed shapes of distant galaxies, a cosmic shear due to gravitational lensing, can be used to simultaneously determine the distance-redshift relation, r(z), and the density contrast growth factor, g(z). Both of these functions are sensitive probes of the acceleration. Their simultaneous determination allows for a consistency test and provides sensitivity to physics beyond the standard dark energy paradigm.

Probing the independence within the dark sector in the fluid approximation
