POMODORO and External Libraries of Excalidraw

It will report an error when I load the external library file of the excalidraw. Is it not available or is there something wrong with my computer? (for win 11 and the logseq 5.0)

And Could you add a POMODORO like the POMO in the roamresearch?

There is a plug-in for Pomo for you can install from here
