I have checked on the installation steps and I am following all the necessary steps but after that also it is not successfully deploying that is the reason I am putting my question here.
What specifics would you need?
I am also getting in touch with TestRail support team for the issue. But the plugin I am trying is free trial version of the TestRail so there should not be any issue with the versioning but need to check if I have missed any important steps for the installation.
Thanks and Regards,
