The verse centers on "people", "rejoiced", "offered", "willingly", "perfect", and "heart". It is saying that the verse draws attention to "people" and "rejoiced", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "People with whom precious stones were found..." into verse 10's "Therefore David blessed Yahweh before all the...", so "people" and "rejoiced" belong inside that flow. In 1 Chronicles context, the local focus is covenant, worship, and faithfulness.
