How to display time in Metabase Embed Signed Iframe?

We have a situation where someone, who is in a different timezone (US-Central), is looking at charts that we have embedded as a iframe on a React app and sees times that are in US-Eastern. The charts all leverage date/times that are in UTC and display correctly for our (developers) timezone (US-Eastern). Is there a way to pass in a timezone field into the iframe or is there a setting that we have to enable? Thank you in advance!

You need to use data sandboxing here and pass the time zone as a parameter, so Metabase does the time zone conversion when executing the query to each user
