The fieldKey 'channels' should be 'channel' (singular) to match the actual field name defined in the schema.

Suggested change

	{
	fieldKey: 'channels',
	fieldKey: 'channel',

The test description contains a grammatical error. It should read 'should be hidden when flag is disabled' or 'should be hidden when flag is not enabled'.

Suggested change

	it('channel for Facebook Messenger channel option should hidden when flag enabled', async () => {
	it('channel for Facebook Messenger channel option should be hidden when flag is not enabled', async () => {

Just left couple of comments. Also, it seems like codecov/patch is failing because test coverage isn't sufficient enough. pls see if we can increase test coverage
