      abstract     = {We discuss an ongoing first lattice study of the
                      doubly-charmed tetraquark $T_{cc}^+$(3875) via a three-body
                      approach. We investigate the $DDπ$ system in the $I=0$,
                      $C=2$ sector, where the $T_{cc}^+$ appears as a pole in the
                      $J^P = 1^+$ $DDπ$ elastic scattering amplitude. The
                      approach automatically incorporates two-body $DD^*$ and
                      three-body $DDπ$ effects and treats left-hand cuts due to
                      single $π$ exchanges. Two CLS ensembles, X252 and X253,
                      with pion mass $M_π\approx 280$ MeV, are used, and an
                      operator set comprised of two- and three-hadron and
                      tetraquark operators is employed to extract finite-volume
                      energies. Additional inputs are required for the three-body
                      finite-volume analysis, in the form of amplitudes for the
                      $I=1$ $DD$ and $I=1/2$ $Dπ$ two-body subsystems. We present
                      preliminary results for these subchannels and perform
                      exploratory three-body spectra determinations for simple
                      choices of the three-particle K-matrix
                      $\mathcal{K}_{\text{df}, 3}$, allowing a first comparison to
                      the lattice spectrum.},
