Zwift Hub and new cog 2

Hi, I’ve just upgraded to a Zwift ride frame and cog2 (orange face), had to remove the cassette from my zwift hub and replace with the new cog. This cost me a few quid because Zwift don’t tell you this when you upgrade.
Anyway I managed to do the change however I need to know if I need dropout spacers in order to mount the frame properly? I didn’t get any with the delivery. I’m no bike mechanic so new to all this. Got on the bike this morning and there’s a lot of play and noises coming from the cog area…. Please help as I don’t want to damage anything
