Question: How do I assign a graph to another graph without referencing in Maple?

Hello, which operator should I use instead of ":=" (assignment statement) so that the graph H remains unchanged in the code below?

with(GraphTheory);
G := CompleteGraph(4);
DrawGraph(G);
H := G;
DeleteEdge(G, {1, 2}, inplace = true);
DrawGraph(G);
DrawGraph(H);
