Hey @xristos3490,

I tested this PR and confirmed that after your changes, when HPOS is used:

• The additional Extensions > Orders tab is removed and;
• The Orders menu item points to the correct wc-order URL.

Manually tested with @jimjasson and code reviewed (pushed a commit to avoid back and forths)

Thanks for this - awesome! Merging and will ship later in the day
