Add "brainstorm"/"Annotate" mode in regular Figma files

This isn’t just an Idea. Consider it a feature request, as it is painful not to have this in Figma. 🤕
When discussing design options with a team, we often try to sketch ideas or highlight parts of the design as we discuss or review designs. However, using the current pencil feature brings a mess to the designs (it’s hard to remove all those lines from the designs, and sometimes small “lines” or “dots” can be missed). Adding a specific Brainstorm/Annotate mode (similar to how it works in Zoom) would be great so users can switch it on and annotate and sketch their ideas and thoughts. If there is a need to save sketches at the end of the discussion. It could be saved as a separate FigJam file.
