Fill popup field use Autoit script in selenium test

[qqq1]

I need to fill popup log with Autoit script help. Problem is that, when I open link with my selenium test, Chrome is being controlled by automate test software and it is impossible to fill popup logs, but when I simply open my link in browser and after that I use Autoit script, popup logs are filled with necessary date. 

This is my Autoit script:
Send("username")
Send("{Tab}")
Send("password")
Send("{Enter}") 

I tried added WinWaitActive and WinActivate functions, but it didn't helped. I hope someone can help me with this question.
