Adding a hotspot use interaction in code

bud

I am trying to add a hotspot use interaction in code.
I have successfully added buttons to the use interaction, but nothing shows in the inspector before I press the + sign button on UseInteraction, then I will see the added button.
Seems like there is some kind of update/refresh needed, but what ?

Note: If I set any other Hotspot settings (above Use Interaction) they are showing correctly.

Set the Hotspot's provideUseInteraction bool variable to true.
