How to Enable Open GApps in FydeOS v18 and Later Versions?

Hi. I’ve just installed v18.1 on a Raspberry Pi4 and all seems ok except. Gapps/Play Store
Firstly I don’t see the developer mode toggle in steering however I can still access the shell. Once in the shell I don’t see crossystem_mode-switch in /usr/sbin.

When I try to launch the play store it asks me to sign-in a large progress wheel starts to rotate and eventually hang.

Any suggestions ?
