It usually heats up the filament, then pulls it back (retract), then allows it to cool down then you can pull it out
you feel the printer does not unload the filament when the Hot End is hot, it waits letting the Hot End cool down to 133C then it tries to unload it because the pulls back (retract) step is difficult and did not work.
I would wait it reach 230 and apply a little force on the filament to help it gets out before it start to cool down. If you can not get it out when it heat to 230, you have a jam, take the hotend out and clean it.
