You can create a store like below and add c custom data channelData , i have used simpleUpdatein Package for it

const store = window.WebChat.createStore(
            {},
            ({ dispatch }) => next => action => {
                if (action.type === 'DIRECT_LINE/POST_ACTIVITY') {
                    action = window.simpleUpdateIn(action, ['payload', 'activity', 'channelData', 'myData'], () => myDataObj);
                } 
                return next(action);
            }
        );

Then inject this store to directline instance like

window.WebChat.renderWebChat({
            directLine: window.WebChat.createDirectLine({
                token:  '@Model.Token', 
            }),
            userID: '@Model.UserId'
            store, 
        }, document.getElementById('webchat'));

Now in Bot side you can access it under context object ,full path below

dialogContext.Context.Activity.ChannelData
