Regarding the first words/speech of Allah سُبْحَانَهُ وَتَعَالَى on judgement day

since childhood we keep hearing that on judgement day our creator will judge between us, more specifically, talk to us and have (secret) conversations with us. this talk and conversations as i understand includes mainly questioning (about our sins). until recently i did not know there was a record/narration/hadith regarding the first words/speech of Allah سُبْحَانَهُ وَتَعَالَى to the believers on the day of judgement. can someone from the community please enlighten me about this. is this true?, if so what is the narration/hadith?
