STM32 power consumption in reset

I would need to know how much power does an STM32G0 consume when kept in reset by pulling down the RST pin.
Is it specified somewhere?
I'm afraid it might be more than what the part uses running a well power optimized software, right?

    That doesn't answer the question, "what happens while nRST is asserted (held low)?" - which, I think, is what @EeroHeikkinen was asking.

    Unfortunately this documents doesn't say anything about consumption in reset. 
    Anyhow, after reset the device starts in RUN mode, so I take the assumption that in reset it's prepared to run and  consumes nearly the run mode power.
