How to increase the spinning speed of QML Tumbler?

[QTLeearn]

Hi, I am implementing a QML Tumbler:

Tumbler
       {
           id: tumblerHrId
           model: 24
           delegate: delegateComponent
       }

When the Tumbler is completed(loaded) I want to assign its currentIndex value. As a result, on starting up the Tumber spins, but the spinning speed is lower than I want. There are solutions that can skip the "startup spinning" animation effect, I would like to keep the "startup spinning" , but to increase the spinning speed, is there a way to increase this speed?
Thank you in advance!
