Firebase dynamic link support custom parameters?

Question

I am writing a App for a Open Source Conference.

Originally each attendees will receive different link via email or SMS like

https://example.com/?token=fccfc

Answer 1

I don't think you can use the short url: https://.app.goo.gl/Gk3m unless you create one for each user, but you can use the long url: https://.app.goo.gl/?link=https://example.com/?token=fccfc8bfa07643a1ca8015cbe74f5f17 ...(add other parameters as needed) and set new token for each user.

I assume you generate the tokens automatically. In that case you can use this to shorten the links.
