Press its icon in the toolbar. The popup opens on Shots.

That is the only choice you need to make for this kind of shot.

It scrolls the page and joins it into one picture. A sticky header shows once instead of on every screen, and scrollbars are hidden.
補足
A very long page is captured in parts and joined: one PDF, or numbered picture parts. Settings, Shots has full width for wide pages, and loading lazy content first.
The whole page opens in the Shots editor. Add arrows, text, blur or a crop if you like.

The export panel opens over the editor.
One capture writes each format you tick.
補足
The PDF keeps the page's text selectable and searchable. Searchable PDFs: 10 a day on a free account, 5 signed out, unlimited on Premium. Past the limit the PDF still exports, as a plain picture without the text and links.

The files land in your Downloads folder.
補足
Every capture is also kept in the Library. Downloads are copies.
