[Решено] multi domain cloning

Background of the issue:
I have cloned my website to another domain for testing purposes and it says that I need to share credits and paste the migration code in order to keep running both websites. The screenshot 1 provided it says follow this link and it redirects me to the original website as shown in screenshot#2 its shows credits left. So what should I do so it not effect the original website and I can use the clone as well?

Symptoms:
I need guidance on where to find the migration code and information on total credits used and remaining.

Questions:
Where can I find the migration code?
How can I check the total credits used and remaining?
