I need an expert in SumSub API integration

I need an expert in SumSub for API Integration. We have a full development team who has built our platform but they are not able to install sumsub correctly.

I am getting a lot of repeat requests from the same user, and they tell me it’s impossible to resume an application which I have done on sumsub myself many times.

What I need is

Sticky banner telling users to verify themselves on login in for verified - Done
Once clicked it takes you to a Verification part in “My Account” - Done
This will show a cross to show unverified - needs completing
Once clicked it will open an iframe to start the sumsub verification - not done
Once the sumsub verification is done, it will show a spinning hour glass to show the verification is processing - not done
Once complete it will get a tick symbol to show verified - not done
If failed, it will show as failed and allow the user to click on and correct whatever document or part failed - not done
The process will repeat indefinitely till the user is verified.
