Web scraping

Hi I have been breaking my head on this for past year. I have managed to open a web page with vba code but I now need to expand the organisation structure under my teams and copy all the content on a excel file.
Problem is that each direct manager under me has another manager for which there is a + sign against each name which I need to click each time to expand the organisation structure. I am not able to find how to click that + sign which will show the teams under them.

That seems to be obvious.

Could you assist please. This will help me a lot in the daily work.
