Please can you implement "+ Send" for egui_plot PlotItem

Hello, I need to use egui_plot PlotItem across threads, basically my Rust code is to generate an oscilloscope trace from SPI input using egui::Plot. Without using a thread to draw the trace, the oscilloscope trace drawing is far too slow. The error message I'm getting is as follows:
error[E0277]: `dyn egui_plot::PlotItem` cannot be sent between threads safely
= help: the trait `Send` is not implemented for `dyn egui_plot::PlotItem`
= note: required for `Unique` to implement `Send`
note: required because it appears within the type `Box`

I have researched implementing "+ Send" as part of my code but it would appear it needs to be implemented in the PlotItem library/source, I have tried just about everything to get PlotItem to work across threads and am tearing my hair out! Many thanks in anticipation.
