How can i forbid to type text in mention input without disabling?

[lactivka]

I have local message state
const [message, onChangeMessage] = useState('')
Value of message changes by input. When i send message i need to clear input and forbid type new value without disabling the input field (because disable state makes keyboard close, but it must be always open)
I can do this with TextInput from react native by passing in props this onChangeText function

onChangeText={
            val => {
		if (!isSending) {
			inputRef.current.clear()         // clear input by ref
			onChangeMessage('')           // clear massage state
		} else {
			onChangeMessage(val)
		}

It prevents typing new text in input while prev message is sending.
But if i pass same function to onChange prop of mention input it not works and i still can type text and change input's value. In the same time local message state not changes, it is empty string while is sending
