Hey @bozzelliandrea that looks great! Might I ask you just one change? At the moment, in order to track all the changes that we're doing (we don't want to diverge too much from the original repo), we're including a OGCIO comment on every change we make. If you search for OGCIO in the codebase you can find multiple examples. Can I please ask you to stick with the same pattern? That helps us a lot during the versions update :)

Hi @alfonsograziano , thanks for the feedback, I added some comments for the lines introduced with the feature.

LGTM - just on a side note, next week we will have a pen test on Logto and we would like to NOT merge PRs (if not critical).

Would it be fine for you to keep this one opened and ready to be merged as soon as we complete the pen test?

It will be on the Staging env (so Dev shouldn't be affected), but still would be ideal to not introduce any change in the code for the moment being

Sure no problem, @alfonsograziano we merge after pen-test.

Setting this PR to draft to avoid accidental merges.

Let's wait for the o11y sdk package to be ready for release before reworking this PR to avoid having to heavily refactor this later on.
