How can I Prefill live chat form apart from email and name

I’m trying to prefill organization name on the live chat form. I’m able to pass the name and email in the URL to prefill the form.

However, the organization name is an additional field I’ve added but it doesn’t get prefilled like name and email.

Is there any other way to profile additional form fields on the form similar to name and email?

Hello :wave:

Unfortunately, prefilling works only with name and email (link)
If you would like to send more info about your users, Custom variable seems like the only option (link2) but it will be showing only in the chat details, but not in the pre-chat form.
