How to come back to Dubai after deportation and ban for visa overstay?

Dear Sir/Madam,

My wife was working in the UAE from 2016 to 2018 and completely finished her contract. She got the cancelation of the papers from the company then she moved to another company.

But the new company visa process got late from the date of the paper cancelation. So it expired and she did not exit the country at that time for more than 1 month.

She went to her home country and she faced immigration at Dubai airport. They deported her for absconding and gave her an immigration ban. I tried in 2021 to get her a visit visa but that was also rejected.

My question is how to come again to Dubai?

Any possibility to check that at immigration?
