Trying to make a link from a task in a mermaid gantt diagram to a page in joplin:
click task1 href "joplin://76ae32f7854d42488c4040c68c8ddd3c"
I place that line at the bottom of the mermaid stanza and get a clickable 'task1' in my gantt diagram. Problem is that windows asks me what application I want to use for 'joplin://' url.
Do I need install a plugin or set some configuration option?
I am using:
Joplin 2.3.5 (prod, win32)
