If you are using local Excel file then no need of those things, but if you want to edit the OneDrive Excel files then those are required because first you / your bot has to authenticate with the OneDrive then only you have the access to your excel
If you don’t want all these then you can always make available the excel file into a shared drive and then you can use the Excel activities
If you have the excel available locally then don’t use the Microsoft 365 activities you can use the below activities
As I see there is no Range Color in the modern design activities, so you can use classic activity for that, this will enable the classic activities as well
Alternately…if you want set range color only then click on activities → filter icon-> classic…then from
The classic excel activities you can see the set range color as well
