I must be blind: modify playback tempo


I am trying to alter the tempo whilst playing back a piece in Dorico.
So far I can change the mode between fixed tempo and not fixed tempo - but I guess this has to do with recording a piece. Where are the keys to manipulate playback tempo?
Thank you for help.

You can’t currently change tempo while Dorico is playing back.

Thank you Daniel, as a workaround I’ll access the properties temporarily.
