What if any role did the series “Servant of Nation” play in getting Volodymyr Zelenskyy elected as President?

It is well known that Volodymyr Zelenskyy was a television personality before he became President of Ukraine. He played the lead character in the Ukrainian television series Servant of the Nation

It is not uncommon for television and movie personalities to successfully move into Politics, some examples being Donald Trump, Ronald Reagan, Jayalalitha, Jaya Bachchan, Hema Malini etc; but different political cultures have different rules which influence such elevation of an actor to a politician.

In the Ukranian political culture, how influential was the role of his TV career in getting him elected? Did he have any other contributions to the politics of Ukraine, which also played a significant role in getting him elected?
