Custom STWLC38JRM LC circuit design

Hello,

I'm working on implementing a wireless receiver charger design using your STWLC38JRM, and wondered if there were any tools or otherwise references to changing the supplied example BOM. In particular I'm looking to change the inductance of the coil as the 8uH specified has only one possible product currently available on Digikey and it is quite expensive per piece. Do you have any tools/references/simulations/etc. for tuning this LC circuit?

Dear Customer

Our WLC GUI includes the Coil selection tool where you can put
the parameters of coil and the tool calculates approximately the Ctank. The GUI is available on https://www.st.com/en/embedded-software/stsw-wpstudio.html

The GUI link above still gives a "Page Not Found" error.... I still need the LC tuning software as the user describes above.
