Dreame X60 Ultra Mop Holder

Hello I have a brand new Dreame X60 Ultra robot cleaner but the accessories pack was lost in transit while being installed into a new home.
It looks like I can buy all of the items separately online except the official Mop Holder for the X60.
Dreame support has said that's correct they don't sell them individually.

Has anyone used a generic mop holder on this vacuum cleaner? I've read they might not be as good and the fitting tolerance can be off on some orders.
I don't want to void any warranties because it's a brand new robot.
I'd prefer to buy an official one but Dreame doesn't sell them, which I find weird?

Any help would be appreciated
