If you come to Poland in 3 days you have the digital passport...
if you make it trough the Embassy you will have to wait months... and politics... EU don't like new foreigners
The embassies wait 3-4 months to collects documents and they send them so the best reaction time is about 6 months... but remember they only work as a delivery company and won't solve any problem, besides, Embassies are political extensions and if they want they will make you problems
Better come as a tourist and do it yourself!
The confirmation that you have received if you'd did it in Migration in Warsaw only takes 7 weeks!
