Virgin Media User with existing Nighthawk AX8 wifi mesh extender - all working fine - want to extend

current setup working great WPS paired the extender to the VM router and everything is good - want to send wifi to garden studio too. Looks like best option is to purchase another Nighthawk AX8 wifi mesh extender and set it up as an access point? (I have the capabilty of hardwiring 2nd unit yet to be purchased directly to VM router with CAT6 cable through the garden to the studio). Pretty sure you cant daisy chain the extenders?  Anythign i might have missed? in summary i would have VM router Wifi extended wirelessly by extender #1. Extender #2 would be hardwired , set as an access point and woudl be called a different SSID too (this isnt a problem for me) I want MESH in the house and dont mind swapping to another access point Wifi name when i am in the garden or workign from the studio (pretty sure the extender #2 (aka access point) would send a good signal out to the garden ).
