Live 11 suite change tempo mid song

[MusicGaz]

Hello all,
I'm new to ableton using Windows 11 and ableton live 11 suite, I've looked at YouTube videos and I can seem to find the one that matches my version/layout..
So there was a video showing master track and under arrow mixer.. however mine had two boxes showing 1/2 and 1/2 not mixer if I go into configure it gives a whole mess of options..but not sure what I need..
So all I want to do is increase bpm mid song in a gradual build up.
I see there is an option to add timings from 4/4 etc but nothing to do a gradule incline.
Sorry if it's bee asked before, maybe I'm not asking question in the right way.
Hope someone can help.
Thanks in advance

Hi, if you’re in arrangement view press A to open automation and that will give you the options you’re looking for.
