Delay in sandbox request approval

Dear Team,
I am Rajat Rawat, Co-founder of Arkade Healthtech Private Limited.
We had raised a request for permission for the sandbox on March 11 and haven’t heard anything from the team.

We are exploring to create API bridges to flow the data between HIUs and HIPs and to subsequently provide API services to HIMS to do Health ID and Doc registries.

Can someone pls help on this?

Thanks in advance
