I think you are more talking about RUM which isn't yet supported by OpenTelemetry. I think they are working on it. I am not sure if it will support session replays like some vendors like Sentry or New Relic offer. Technically, I think session replays (rrweb etc) is pretty cool but as a web visitor I am not a fan.
