Why is Michael mentioned in an end time prophecy detailing the resurrection and the judgment if he is not Jesus Christ?

The angel Gabriel foretells what many Christians interpret to be the Great Tribulation, followed by salvation of the saints and the judgment of the wicked. **Daniel 12:1-3** >“At that time Michael shall stand up, The great prince who stands watch over the sons of your people; And there shall be a time of trouble, Such as never was since there was a nation, Even to that time. And at that time your people shall be delivered, Every one who is found written in the book. 2 And many of those who sleep in the dust of the earth shall awake, Some to everlasting life, Some to shame and everlasting contempt. 3 Those who are wise shall shine Like the brightness of the firmament, And those who turn many to righteousness Like the stars forever and ever. How is arch-angel Michael standing up for Israel(or the new Israel) and triggering the apocalypse if he is not Jesus himself?
