How do you reinvest distributing ETF?

I’ve seen VT (Vanguard total world) being discussed a lot. But this is a distributing ETF. Do you manually buy shares yourself whenever they distribute?

Also: many people recommend Saxo in combination with this. Since there is no savings plan for this ETF there is have to manually buy more every month manually anyways right? So then I’d just add that distribution amount on top of it or how do you guys do it?

This seems a bit too much manual labor for me compared to how it used to be for me on German neobrokers (also cheaper and almost all ETFs are possible for the savings plan) but of course there I didn’t have access to VT which should be better in the long run
