Function for Obsidian that returns the block link and embed of a task passed as a dataview task object

readme.md

Function for Obsidian that returns the block link and embed of a task passed as a dataview task object, for example from the nextActions.js function. Generates random block IDs, if the task doesn't have one. You can also specify a custom block ID, instead of generating a random one.
