let username: String

VStack {
// Search bar
HStack {
TextField("Search", text: $searchText)
.textFieldStyle(RoundedBorderTextFieldStyle())
Button(action: searchForFriends) {
Image(systemName: "magnifyingglass")
.foregroundColor(.blue)
}

chatManager.addMessage(Message(text: messageToSend, sender: username))
messageToSend = ""
