When you start recording a meeting, you also turn on live transcriptions (if your IT admin allows transcriptions). Start or join the meeting. Go to the meeting controls and select More actions > select Record and transcribe, then select Start recording. Everyone in the meeting gets notified that recording and transcription have started.

You can download the recording from the meeting details and upload it manually to Microsoft Stream after the event. To manage the reports, click Calendar, select the live event, and go to the Event resources section. To download a recording or report, click Download next to the item. To delete all the listed items, click Delete all.

The recording will be available after the meeting was scheduled to end (so not necessarily when it actually ends). If you were part of a scheduled meeting, go the Details tab of the meeting event in your calendar and select the recording. If it was a channel meeting, go to the channel conversation and select the recording.
