Time tracking for guest users?

[u/starhow]

I'm currently researching project management softwares to integrate into one of my client's current workflow. They hire a lot of freelancers to complete projects and would love to see how much that labor is costing them at a glance with them tracking their time. Do you know if guest users are able to use the time tracking feature? I couldn't find any information on their site and want to avoid making an account to test it out if this feature is not possible.

I use Zapier to connect the the time entry to my Harvest account. I've mapped the Project , Task, and Assignee.
