Configuring client-side certificates?

Hi there
Does anyone know how to configure client-side certificates in plug-in builder?
Specifically, I have a client side certificate and key, with the key having a passphrase.
I can use them in Postman, which allows these three items to be configured for calling an API.

In Bubble, I can see how to paste in certificate and key content in the API section, but I can’t see how to enter a passphrase.

Thanks, Rob

HI, did you ever figure this out? I have the same problem

Any success on this? Also looking for a solution…
