Which Isofix car seats fit the Puggle Monaco XT 2 pushchair frame?

[CluelessSendHelp]

Hi!
Weve been gifted the Puggle Monaco XT 2, but want to replace the car seat with something isofix compatible/better than the one that it comes with.
Has anyone had this pushchair and know which brands/models are compatible with the frame? TIA!!

It looks like it has the car seat adapters which are a sort of chunky 3D "U" shape?

Those go with any infant carrier by Cybex, Maxi Cosi, Joie, Nuna, Besafe, Britax or Avionaut.
