It is up to the remaining representatives whether to seat the newly elected.
*****************
In the House are there any “remaining representatives’”, since they all stood for election? Or do those who were reelected decide whether to seat the newly elected members?
That is a very good question. Since House members are up for election/re-election every 2 years, that is the only explanation that makes sense.

The bodies of up to 800 infants are to be exhumed as part of an investigation into religious abuses in the Republic of Ireland.
It follows the discovery of “significant quantities of human remains” on the site of a former mother-and-baby home near the town of Tuam in County Galway in 2016.
The members who were not elected/reelected convene the new Congress (agree to seat incumbent members). They then agree to seat the new members.
Members who are re-elected are considered anew as their “term” closed at the Ned of the old Congress.
Ostensibly, the members “carried over” could deny seating to others at the convening but that would cause an election crisis. As would denying in-coming members.
