A structure is developed around their thresholds, short of producing a bound state, which leads to a peak in the $D_s^+ \\pi^-$ mass distribution in the $B^0 \\to \\bar{D}^0 D_s^+ \\pi^-$ decay compatible with the experimental data. We conclude that the interaction between the $D^*K^*$ and $D^*_s\\rho$ is essential to produce the cusp structure that we associate to the recently seen $T_{c\\bar{s}}(2900)$, and that its experimental width is mainly due to the decay width of the $\\rho$ meson.
