Please provide trail key for data validation which we used earlier

Hello Team,
 
I hope you are doing well.
 
We got one request from client to enable dashboards.
 
Last time we validate the data and could not able to provide any demo.
 
Below are the details, could you please provide free tails or extension for demo.  [domain name] - 
[license key]
 
we want to renew license for this after data validation.
 

Thanks,
Vasu
