Dynamic Chance OptionPicker

[Balowser]

Hey,
i have an optionpicker with some fixed values.
Now I have a form which fetch ghe data from an api.
Now i have created a update sidebar. When I click on a row all values should get shown in the sidebar.
All "normal" fieles ware working. But not I habe a Boolean-Column in the form and want that the option picker gets the value of the boolean field of the clicked row.

I tried it with the Update Field Action, but the picker don't change.

Could someone help me?
