  We report on the implementation of a new NNLO+PS event generator for the
Higgs production via bottom annihilation using the MiNNLOPS method in the
POWHEG framework. The calculation has been carried out in the five flavour
scheme (5FS), where the bottom mass is neglected. We compare our results
against fixed-order predictions at NNLO as well as resummed predictions at
next-to-next-to-leading-logarithmic (NNLL) accuracy. We also present a
preliminary study in the four flavour scheme (4FS) setup, achieving a new level
of precision in the massive scheme.
