Profile views, connection requests and messages in a sequence are carried out by the extension, in your Chrome, when you say go.
In Message Center, open "Scheduled today". LinkedIn steps are grouped by sequence and step like email.
Click "Run in Chrome" on the LinkedIn group. Each person shows "Up next in Chrome" or "In today’s Chrome run".
Chrome opens a tab in an "Artra" tab group and works through the profiles one at a time, with a human-like pause between them. Keep the tab visible; it pauses when hidden.
The side panel shows the live run: what it is doing, with pause and stop.
Back in Message Center, open "Scheduled today" again.
Back in Message Center the rows update as each view or send completes. Daily LinkedIn limits are enforced per account.
