Show questions based on embedded data URL?

Hi, I am creating an approval flow based on this post:

https://www.qualtrics.com/community/discussion/2334/creating-a-single-survey-for-a-series-of-responses-from-different-respondents-ie-approvals

Which allows the re-take link to be used as part of an approval flow ie retake link sent to third party, appended URL to show new questions.

For example: https://sydney.au1.qualtrics.com/jfe/form/SV_9BJGnqtEot0aiTH?Q_R=${e://Field/ResponseID}&Q_R_DEL=1&Approver=1

I am able to append the link and refill the survey information fine, but I am having trouble getting my survey questions to show according to my custom embedded data called "Approver".

I can hide my blocks ie: access request + supervisor approval - but I can't show them again even when the URL has the approver value in it.

I've looked at the documentation and it's still not clear to me.

Where in the survey flow do I put my embedded data Approver field?
How do I get my Approver blocks - " access request + supervisor approval " to show based on the URL which will have Approver in it?

Attached are some screenshots of my flow - thanks.
