Government employee sponsoring family visit visa for adult daughter and grandchild

Hi everyone, posting this on behalf of my father.

I’m a government employee in Kuwait and I’m planning to apply for a family visit visa for my daughter and her 4-year-old child.

My daughter is 31 years old.

I have a couple of questions and would really appreciate advice

As a government employee, can I sponsor a family visit visa for my 31 year old daughter and her 4 year old child (my niece)?
Do I need to apply through Amal Al-Doula (عمل الدولة) because I work in the government sector, or do I just submit the application at my area’s Jawazat.
