Click "Highlight" on the VOD you are editing in Premiere.
Click the three dots in the bottom right corner.
"Download Clips Data (.csv)" only contains Clips from Editors so I always download the "Top Clips data".
ℹ Users with Editor role or above can also download Twitch clips and marker data. So you don't have to download it and send it your editor. Editors can just visit the URL: dashboard.twitch.tv/u/CHANNEL_NAME_HERE
Twitch Clips & Marker Importer Extension for Premiere Pro
Insert the entire Twitch VOD into your sequence first!
Open extension panel (Windows -> Extensions).
Select or Drag & Drop .csv file(s).
Choose marker color(s).
Click the Import button. You can choose between two targets: current sequence or selected clips.
What's the difference?
Premiere Pro Clip Markers VS. Sequence Markers
Premiere Pro Clip Markers VS. Sequence Markers
I recommend using clip markers because sequence markers will desynchronize from your video when moving clips by mouse.
⚠ If you still want to work with sequence markers, I highly recommend to enable "Ripple Sequence Markers" to prevent them from desynchronizing when using "ripple delete":
