Support sending command to activate Fresh Care or KeepFresh mode after a wash has started

[sandymac]

Is your feature request related to a problem? Please describe.
I'd like to be able to enable the Fresh Care aka KeepFresh mode when the wash is running and nobody is home. The mode can only be enabled after a wash/dry cycle has been started. This mode will keep the laundry active to prevent wrinkling until you can unload the machine.

Describe the solution you'd like
The mobile LG ThinQ app allows you to toggle the mode on. I'd much rather HomeAssistant to turn the feature on for me. For this to work device controls will need to be exposed.

Describe alternatives you've considered
I don't see the KeepFresh/Fresh Care button's state reflected in the Device page as either a control or sensor so I don't know how to approach a home assistant alternative.

Additional context
I've attached several diagnostic downloads and it appears "laundryCare" is the json attribute that changes when I toggle the button in the app. You can see this change between each of the 3rd to 6th dump.

Fresh Care
Use this function when you will not be able to unload your clothes immediately after the wash cycle ends.
The drum will tumble periodically for up to 19 hours to prevent wrinkles.

+1 Came here to request exactly this. My LG WM6700HBA has 2 different versions of this. "Fresh Care" which can be enabled when a cycle is started or a "Keep Fresh" which can be triggered form the app after a cycle is finished. I'd like to be able to trigger a start keep fresh on a cycle after it finishes if the door isn't opened within 10 min.
