Sentry requests using http/1.1 instead of H2

Hi,
New to Sentry, Using Sentry in a react UI.

Noticing all my Sentry requests are being sent using http/1.1 while all other requests in my application are using the H2 protocol.
(H2 is enabled in my environment so wondering why sentry is reverting to using http/1.1 )
Anyone know how I can update Sentry to use H2 instead of http/1.1?

Looking through the documentation but not having much luck at the moment, will keep looking.
Anyone have any experience using Sentry and protocol 1/1 or H2?
thanks,
A.

(using sentry/react 6.2.1, sentry/tracing 6.2.1, react 17.0.1)
