How to extend your stay in the UAE upon termination and cancellation of visa?

In the month of April 2021, I received a 30-day termination notice.

The company informs me of the visa cancellation, but there are only a few flights to India at this time. In addition, I must spend 14 days in quarantine in a hotel in my home country.

When I explained the situation to them, they advised me to apply for a visit visa once my visa was canceled.

Please let me know if any rules have changed as a result of the COVID-19 restriction/situation.
