How to interact with elements not in the DOM in VBA - excel

Question

I have a problem with accessing 3 buttons on a webpage since they don't belong to the DOM and I cannot fetch them using ID or any other "anchor". These are ActiveX buttons from what I can see in the DOM tree, but I have no idea how to reach to them.
As for now, the only (stupid) workaround is to loop through all the items using on the page by SendKeys {TAB} and pressing space on each of them. Only those buttons react to the space key, but it's not a reliable solution, so I want find something proper.
I'm attaching the DOM screen from the area where they are placed on the page and the code where I think there are sitting.
