I have a Galaxy Watch 4 and use Macrodroid to launch some macros to open my garage door, turn on/off lights in my house, etc. I would ask if Macrodroid could be updated to allow for a Tile Screen on my Watch.
I also tried using the ParseTask Tasker Plugin in Macrodroid with no success. It would be nice for the Macrodroid developer to add the ability to parse JSON data as a built-in feature in the text manipulation/extraction. Just an improvement suggestion.
