The Vienna Philharmonic demonstrated it with their New Year's Concert: This is how people clap when no one else is in the hall.

Thousands on tablet, smartphone or laptop.

All registered.

It could be silly or tomorrow's applause.

While on January 1, 2005, because of the tsunami in Southeast Asia, which killed 228,000 victims, the “Beautiful Blue Danube” was foregone in the finale for reasons of piety, but not the Radetzky March, which was enthusiastically applauded by the audience, in 2021 you have to be more creative. The big applause at the end of each half of the concert is not just what you want to play from tape, as you know it from comedy programs and sitcoms, from television.
