Problem Uptime Robot

Hi,
I have HASSIO with 2021.8.8; when I go in configuration->integration->add integation

I’m not able to find Uptime Integration…

I also tried to use myIntegration feature available here:

It answer: " not possible to load flow"

What I have to do?

Home Assistant OS has not been called Hassio for nearly two years. Please stop calling it that.
