Is TikFlowRPA safe?

TikFlowRPA lets a locally installed automation app drive Chrome pages on your behalf.

The extension connects to a native messaging host ('shadowbot.chrome.bridge') installed on your computer, then uses Chrome's debugger and scripting APIs to run automation commands sent by that app across your open tabs. The only way to trigger this is through the locally installed companion app itself — there is no way for a website to send it commands.
