Contact centre agents work on shared desktops. Some of them in AD, some not (a terminal server which is not in AD).
Contact centre agents work in a CRM system (web based app) and calls via API an unattended bot which gets login password from a DB and type it on personal profile pages on different sites (web pages).
How I could send bot to be executed on operators desktop. The bot open chrome and types login\password and leaves it open for operator to continue working with the profile.
The CRM system not in AD, no SSO authorization yet, but we could do it if it is a solution.
I would suggest very high level solution to use Orchestrator API to achieve this.
Please refer this one for more in detail POC.
Thanks,

yes, API, but how I could get hostname of the desktop. Agents could press the button from a browser on different desktops. I have to open via API a new tab on the same machine.
