Has LW001 said, you need monetization enabled and then you should check the dashboard for an update, if nothing happens in a few days, message me privately and I'll get support to look at it
Also don't forget that on top of the monetisation, as mentioned by LW001 and itsjustjord, that your channel needs to currently be active, with at least some videos on it and set to "public" so that they can be reviewed, as per our process before you can join Freedom.
