Set starting order number

-- HikaShop version -- : 4.0.1
-- Joomla version -- : 3.9.1
-- PHP version -- : 7.2.13
-- Browser(s) name and version -- : all current

I have found how to set the order/invoice number format (in my case to 4 digits) but I can't make any sense of any previous instructions on how to set the starting order number e.g. 2604

I can find the order table on PHP MyAdmin but it's not clear what to do there. I just want to set 2604 as the first order number and then for it to increment by 1 each new order?

Thanks
