Go snippets that use additionalData generate incorrectly

Example 2 on page Create group uses additionalData to add an owner and 2 members to the new group. It shows the following invalid code:

additionalData := map[string]interface{}{
	odataBind := []string {
		"https://graph.microsoft.com/v1.0/users/26be1845-4119-4801-a799-aea79d09f1a2",
	}
	odataBind := []string {
		"https://graph.microsoft.com/v1.0/users/ff7cb387-6688-423c-8188-3da9532a73cc",
		"https://graph.microsoft.com/v1.0/users/69456242-0067-49d3-ba96-9de6f2728e14",
	}
}

Correct code should look like:

additionalData := map[string]any{
	"[email protected]": []string{
		"https://graph.microsoft.com/v1.0/users/d19d82fe-a21d-4f2e-8519-befa248ef769",
	},
	"[email protected]": []string{
		"https://graph.microsoft.com/v1.0/users/d1ac16ce-60f7-4230-b98b-6c7574bb17b6",
		"https://graph.microsoft.com/v1.0/users/37a7dc1b-812b-4336-8210-76b2180b574a",
	},
}
