There is a procedure for inaugurating a King over Am Yisrael:
When Nevi Sh’muel (the Prophet Samuel) anointed the Shepard, David as King over All Yisrael he anointed him with Shemen Afarsimon.
“And the L-RD said to Samuel, “Until when are you mourning for Saul, when I have rejected him from reigning over Israel? Fill your horn with oil, and come, I shall send you to Jesse, the Bethlehemite, for I have seen for Myself a king among his sons.”
And the L-RD said to Samuel, “Look not upon his appearance, or the height of his stature, for I have rejected him, for it is not as man sees, (what is visible) to the eyes, while the L-RD sees into the heart.”
And Samuel took the horn of oil, and anointed him in the midst of his brothers. And a spirit of the L-RD passed over David from that day forth, and Samuel arose and went to Ramah.”
Jesus, a descendant of Nathan, not Melek Shlomo, was never anointed with the Shemen Afarsimon by a high priest or prophet, which disqualifies him from sitting on the Throne of David!
