How can I create a spatial binning similar to or directly using Uber h3 from QGIS UI?
Are there plugins available to achieve the desired task?
You can play with it using my #30DayMapChallenge hexagon demo https://github.com/ThomasG77/30DayMapChallenge/blob/master/day4_hexagons/data/h3-processing.py
Except the fact I do no use an UI, I combine both QGIS and Uber H3 Python library.
I clearly do not use all parts of the H3 Python library. I suppose the example could help you getting started.
New QGIS plugin "H3 Toolkit" unrelated to me but doing more or less the same. Although we provide the link, install it directly from QGIS plugins list.
I adapted @ThomasG77's 30 day challenge script into something that can be run from the Qgis processing toolbox.
Using Uber's H3 hex grid system in Qgis

after Preparation has been completed
There is an error message of "it seems there is no valid script to run", but it works anyway.
Create Grid tool in QGIS, and select hexagons.
For a more thorough, but still brief walk-through, see Jonathan Soma's blog.
(This is for creating a hex grid, it will not be specific to Uber's H3 grids. If you know the positioning and spacing of that grid you could use those numbers with this tool.)
