### Description

Recently the LHCb experiment found evidence for the existence of two exotic resonances consisting of $c\bar{c}uud$ quarks. Among the possible interpretations there is the hadro-charmonium model, in which charmonium is bound "within" a hadron. We test this idea on CLS $n_f$=2+1 lattices using the static formulation for the heavy quarks. We find that the static potential is modified by the presence of a hadron. It becomes more attractive and the effect is of the order of few MeV.
