%X Semileptonic π΅-meson decays involving the quark transition π β πππ provide excellent sensi-tivity to probe potential lepton-flavour universality violation. This work introduces two recentmeasurements related to tests of light-lepton flavour universality using a data sample collected atthe Ξ₯(4π) resonance on the Belle II experiment corresponding to an integrated luminosity of 189fbβ1. Measurement of the ratio of the branching fractions of inclusive π΅ β ππππ and π΅ β π πππdecays and measurement of angular asymmetries of π΅0 β π·ββ ππ decays agree well with standardmodel expectation.
