Why the UIPath Studio I downloaded didn't have the option of App Integration?

Install the packages available from gallery and check.

Thanks for quick response.
I downloaded this form official site(https://www.uipath.com/) and I have downloaded it for three times.
The download process: click product —> studio—> start trial—> get community edition—> fill necessary information—> receive the email with download link—> downloaded.
Then I have the UIPathSetup.exe , and I dbclick it ,there is no setup wizard,just get into the beginning site, I click start free and activate it.
That’s the whole process, maybe the trial version don’t have this activity?

community edition or trial edition does have. click on the packages icon and install the missing packages and you will get it.

Thank you very much! I find it~
