-        amount: 1000,
+        amount: 2000,
+    })
+).to.changeEtherBalance(sender.address, BigInt('-2000'));

+        to: receiver.address,
+        value: 1000,

+This matchers include additional options argument with functionalities for including fee and overriding transaction:

+overrides = {
+    type: 2,
