The token you create with the first ability copies the original characteristics of the token it’s copying as stated by the effect that created that token. The newly created token doesn’t copy whether the original token is tapped or untapped, whether it has any counters on it, whether it has any Auras and/or Equipment attached to it, or any non-copy effects that changed its power, toughness, types, color, and so on.

If the original token is copying something else, the token you create will use the copiable values of the original token. In most cases, it will be a copy of whatever the original token is copying.
(wotc • 2022-10-14)
Any enters-the-battlefield abilities of the token you create will trigger when it enters the battlefield. Any “as [this permanent] enters the battlefield” or “[this permanent] enters the battlefield with” abilities of the copied token or card will also work.

For both abilities, if a token is created copying a token or card with {X} in its mana cost, X is 0.
