### Description

The study of heavy-flavour hadron production as a function of the charged particle multiplicity in proton-proton (pp) collisions allows to study the interplay between hard and soft QCD processes. In particular the simultaneous comparison of open and hidden heavy-flavour multiplicity dependent measurements with theoretical models imposes tight constraints improving significantly our knowledge about the role of Multi-Parton Interactions (MPI).
The ALICE detector provides excellent capabilities to study J/$\psi$ production down to $p_{\mathrm T}$ = 0 in the central barrel ($|y|$ < 0.9), via its di-electron decay channel. In this poster we will present the newest mid-rapidity results on the J/$\psi$ yields as a function of the event multiplicity in pp collisions at $\sqrt{s}$ = 13 TeV, measuring separately the contribution of prompt and non-prompt J/$\psi$. The latter component originates from beauty hadron decays and provides the multiplicity dependence of open-beauty hadron production. The usage of high-multiplicity triggered data will allow to extend significantly the multiplicity reach for both measurements.
