My UiPath Studio is not showing tesserect ocr activity

I have added tesserect ocr activity from manage packages, but still its not showing in my activities.

Hi @arslan_waraich,
We need to have more details. What is the full name of package you have added?

Thanks for your quick response.
I Had added tesserect by charles weld, and it did not worked. Then i tried to add tesserect-ocr by google, but the activity was not installing i don’t know why.
