Presidential Impeachment

It seems like many people are criticizing President Lee Jae-myung, but I wonder why no one is calling for impeachment.
If people dislike him this much, I would expect them to demand impeachment. I feel like if the People Power Party, the Cho Kuk Party, and certain factions within the Democratic Party joined forces, it might be possible. It seems like they could do it the same way they did when the motion for the arrest of Representative Lee Jae-myung was passed. Why is no one saying this?? Have the orders not been given yet?
Also, if they dislike him this much, they could just impeach Lee Jae-myung and split from the Democratic Party, but I don't hear a single word about that. As the saying goes, "if you don't like the temple, the monk leaves"—I don't understand why they stay together if they hate the Democratic Party and President Lee Jae-myung so much.
