Trouble accessing Captions option or Transcript.

I recently received an email confirming my participation in the Beta test of the Speech to text feature in Adobe Premiere Pro. I'm not able to access the options like the instructions mentioned.

Make sure the email associated with your Adobe ID matches the address that received the email invitation.

Besides checking the email associated with your invite, make sure you log out of Creative Cloud and back in at least once to see if the feature has been turned on for your account.
