For what it's worth: The exact same thing happened in Berlin last year -
twice!
The first incident was instigated on August 30 when the protesters of the
Querdenker movement, something like the German "branch" of QAnon, were told by one of theirs that Trump was about to arrive in Berlin in order to "free" them. The mob then proceeded to storm the Reichstag, where only three (!) policemen were put on standby to deny the domestic terrorists access. (Robert F. Kennedy was a guest of honor attending the rally that day, btw.)
The other incident occurred on November 18 when three AfD members of the Bundestag infiltrated Querdenker members into the Reichstag in order for them to harass, insult and threaten members of the Bundestag in the run-up to the passage of a restrictive anti-Corona bill. In the clip below you can see a woman called Rebecca Sommer, a former human rights activist and a refugees' aide, pestering and offending Economy Minister Peter Altmaier (CDU).
