UX: Idle Time Limit misses unit

Description:

In the account preferences, there's an option to enable the "Auto Away" feature and an option to define an "Idle Time Limit". The text box provides no guidance about what unit this time limit is defined in. Based on the number (3600 in my case), a more technical user can probably deduct that the unit is seconds, but it would be helpful to provide some guidance here, at least by informing the user that the limit is defined in seconds, ideally by giving them a way to define the value in a more human-readable way (in hours, minutes, seconds).

Steps to reproduce:

1. Click your avatar icon
2. Select "Preferences"
3. Select "User Presence"
4. Note the input field for "Idle Time Limit" showing a number without any units associated

Expected behavior:

The Idle Time Limit input field should indicate the unit used, or provide a more human-friendly way of selecting a time period.

Actual behavior:

The input fields does not provide any guidance of what to enter here.

Server Setup Information:

N/A (can't provide this information as a regular user on our platform)

Client Setup Information

• Desktop App v4.1.1 on macOS

Start in the account Preferences flow at User Presence and inspect the Idle Time Limit input described in the reproduction steps. Confirm how the current value is entered, then make the unit clear or provide a human-readable time-period control; verify the result in the same flow.
