No OSD in googles

Good afternoon people, I have no osd showing up in my googles. I have a Mamba f722s fc ,TBS Unify pro32 VTX . Everything looks good on Betaflight . I have followed Joshua Bardwell’s video on how to make it work [url][/url]
But no joy, all my other Betaflight osd’s show up in these same googles. And I don’t know what else to do.
Any help would be greatly appreciated .

Are you still plugged in to your computer while doing ghis

Am I plugged in doing which part ?
