First, I went to https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.impl.portal.RemoteDesktop.html#org-freedesktop-impl-portal-remotedesktop-notifypointermotionabsolute. And under the options, it says to "see the logical_size stream property in [ScreenCast](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.ScreenCast.html#org-freedesktop-portal-screencast)". So I click the link, and there's no occurrence of "logical_size".
