The function prop is not working with react

I got the error '..is not a function' when working with react 19
`const ChatWidget = r2wc(ChatComponent, {
props: {
selectedTopic: 'string',
streamingApi: 'string',
chatApi: 'string',
dowloadReferenceApi: 'string',
accessToken: 'string',
onCustomClick:'function'
},
});`

=>onCustomClick is not a function

Start by reproducing the r2wc(ChatComponent, { props: { onCustomClick: 'function' } }) example with React 19 and trace how the function prop is passed to ChatComponent. Done means onCustomClick is callable from the React component instead of producing an “is not a function” error.
