If the above is correct I don't think you will find exactly the adapter
you want. You might have to put a 1/2" tee after the sink's supply valve.
Then you can adapt one port of the tee to whatever the bidet needs. An
alternative might be to adapt the valve to 3/8" compression and replace
the sink's flexible hose with a (common) 3/8" compression by 1/2" pipe
