How to apply gradient conditional formatting?

[and7ey]

I would like to use conditional formatting in my doc -

(https://workspaceupdates.googleblog.com/2015/03/conditional-formatting-improvements-in.html)

There is no GRADIENT condition type - https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets/other#ConditionType. I tried to use CUSTOM_FORMULA - https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets/other#ConditionType - but it didn't help (or I used it incorrectly).

What else should I try?

Looks like this example applies conditional formatting with gradient?

The question is how to repeat it with pygsheets
