thank you @MariaSoledadG  but I'm still facing issues.
The user is a store manager and already has all admin permissions in Workforce and is able to use. However, due to limitations of the app (such as unable to view months), the manager would like to use desktop browser. Unfortunately, we are not able to use the "new" Time in QBO (https://qbo.intuit.com/app/time), as there's no way to set the manager's permission to see QBO Time without also giving permission to other areas of QBO.
However, the legacy/old QuickBooks Time (https://tsheets.intuit.com ) seems to be same functionality as the Workforce mobile app. So, we are trying to invite him to the legacy Time. But, he is getting "you don't have access to this company" message at (https://tsheets.intuit.com ). 
There's no option for Invite like in your screenshot.
