Click button with vba

I need to click a button on a website using VBA. But the button, apparently, doesn't have an id or class defined. Could you help me with a code for it, please?

Where by hell is my crystal ball ?‼

HAHAHAHAH gosh
I guess I didn't provide enough information for the code, right?
I'm new to it, what information would someone need to know a code for it, please?

Did you check at least its XPath ? Its parents as an anchor ?
As without any anchor neither any information I just can say : that's the road end … A bit like ♪ That's all folks ! ♫
