Correct. As far as I know.
The Senate must be informed by a “Letter of Transmittal”.
Here is the Letter of Transmittal for the Constitution.
In Convention Monday September 17th 1787.
Present
The States of
New Hampshire, Massachusetts, Connecticut, Mr. Hamilton from New York, New Jersey, Pennsylvania, Delaware, Maryland, Virginia, North Carolina, South Carolina and Georgia.
Resolved, That the proceeding Constitution be laid before the United States in Congress assembled, and that it is the Opinion of this Convention, that it should afterwards be submitted to a Convention of Delegates, chosen in each State by the People thereof, under the Recommendation of its Legislature, for their Assent and Ratification; and that each Convention assenting to, and ratifying the Same, should give Notice thereof to the United States in Congress assembled.
Resolved, That it is the Opinion of this Convention, that as soon as the Conventions of nine States shall have ratified this Constitution, the United States in Congress assembled should fix a Day on which Electors should be appointed by the States which shall have ratified the same, and a Day on which the Electors should assemble to vote for the President, and the Time and Place for commencing Proceedings under this Constitution. That after such Publication the Electors should be appointed, and the Senators and Representatives elected: That the Electors should meet on the Day fixed for the Election of the President, and should transmit their Votes certified, signed, sealed and directed, as the Constitution requires, to the Secretary of the United States in Congress assembled, that the Senators and Representatives should convene at the Time and Place assigned; that the Senators should appoint a President of the Senate, for the sole Purpose of receiving, opening and counting the Votes for President; and, that after he shall be chosen, the Congress, together with the President, should, without Delay, proceed to execute this Constitution.
That matter is basic to official communication, authenticity. To put it into perspective of the current impeachment nonsense, here's a fictitious dialogue between the leaders of the two Chambers of Congress:
Speaker of the House: “The House of Representatives has impeached the President.”
Senate Majority Leader: “Prove it.”
House Speaker: “I have Articles of Impeachment.”
Senate Leader: “Until I have it, that is hearsay.”
House Speaker: “Everybody knows.”
Senate Leader: “Madam, you jest. You expect the Senate to try a sitting President on rumor?! Prove the Impeachment in the proper manner.”
House Speaker: “What do you require?”
Senate Leader: “The same as always; the Articles of Impeachment signed, sworn, sealed, authenticated, recorded, registered as transmitted by the House of Representatives, and registered as received by the Senate.”
House Speaker: “I think I will hold onto the Articles of Impeachment for awhile.”
Senate Leader: “Then, madam, you have proven nothing. Therefore, Impeachment has not occurred, and the Senate will not convene a trial of anyone. Good day!”
An abuse of power has occurred. It was and is being perpetrated by the House Democrats. Their actions are rising to the level of sedition and treason.
