Hi again, could we add another issue for [opentelemetry-instrumentation-flask](https://github.com/open-telemetry/opentelemetry-python-contrib/tree/main/instrumentation/opentelemetry-instrumentation-flask)? I'd like to take that one too. The change is probably similar to the [recent Django update](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/1730/files).
