The companion has a minimum mass of $26.77^{+4.4}_{-2.2} M_{\\mathrm{Jup}}$ and an expected semi-major axis of $\\sim$ 240 mas making it a suitable target for further characterisation with high-contrast imaging, in particular to measure its inclination, mass, and spectrum and thus establish its substellar nature.
