Sure! Here's a properly formatted and clearer version of your instruction:

---

To enable the highlight floating button feature, update the defaultOptions object in the viewer.mjs build file.

Step 1: Locate this section in viewer.mjs:

enableHighlightFloatingButton: {
  value: false,
  kind: OptionKind.VIEWER + OptionKind.PREFERENCE
},

Step 2: Change it to:

enableHighlightFloatingButton: {
  value: true,
  kind: OptionKind.VIEWER + OptionKind.PREFERENCE
},

This change enables the floating highlight button feature in the viewer.

Alternatively, you can enable this feature through the build settings.
