Problems transcribing meetings and obtaining summaries using copilot in teams

I have been facing problems with Copilot in 365, specifically in Teams, when I use copilot to summarize conversations or calls that I make 1-1 or 1-N I can have the summary of the meeting through the transcript, but when I try to activate the transcript for meetings scheduled in teams it does not allow to activate the transcript, is there any specific configuration that needs to be done?
