Chat Overlay

Apply a saved Chat Overlay theme preset. Future overlay theme packs will use this same picker.

action.change_theme · 2.8.0

Requirements and availability

A compatible saved chat overlay theme.

Picker contexts: automation, timer, command, pad.

Apply a saved chat overlay preset; preset selection is a saved resource ID, not a CSS payload.

Open: Do → Advanced Actions (commands only) → Add action

Choose action category Change Theme, select Chat Overlay, and click Add action.
Expand the action card. Configure the Fields below; check Editor defaults for your context and any operation-dependent fields.
Choose resource values from real app pickers. Set output Platform separately from the trigger Where setting when the action offers it.
Use Move action up / Move action down to position this action, then save the containing command, automation, timer or SheevPad button.

Picker availability does not supply missing event variables. Check prerequisites and originating provider.
An action return value is not automatically a sequence variable. Only documented producers create template outputs.
