SameLabelInstanceGroup Interface
Deprecated in 5.2 - will not be removed until after 2026-10-01. Use the new @itwin/presentation-hierarchies
package for creating hierarchies.
Allows grouping multiple instances with the same label into one ECInstances type of node. Similar to display label grouping, but instead of showing a grouping node with multiple grouped ECInstance nodes, it shows a single ECInstances node which represents multiple ECInstances.
