Hello,

I would really like to use the multiplexing feature but am having trouble because I am behind a work proxy and get the following error:

```
Sending fatal alert BadCertificate
ERROR: Error attempting to provision multiplex token from 'https://reveal-multiplex.glitch.me/': error sending request for url (https://reveal-multiplex.glitch.me/token): error trying to connect: invalid peer certificate contents: invalid peer certificate: UnknownIssuer
```

I do have the certificate that can usually solve this sort of issue with node, I can do something like (from Powershell):

```
$Env:NODE_EXTRA_CA_CERTS="c:\users\---\work-certificate.pem"
refreshenv
some node commands that will require said certificate
```

But I'm not sure how to do this for Quarto when it seems like the issue is talking to the reveal-multiplex site. I guess I could do the multiplexing manually and add the required revealjs commands to the start of the presentation (maybe?) but I would really like to make use of the inbuilt option if it's not too difficult.
