Within the Teamwork Chat Android app, you can set your status to do not disturb to reduce your notifications for a period of time.
DND (do not disturb) can be set manually or for a set amount of time, during which your Chat notifications will be disabled.
To enable DND, select Settings from your Teamwork Chat navigation bar.

To the right of your profile details, press the DND bell icon.

Pressing this will open a pop-up menu with the DND time options.

Once you select a time period, the DND alert will be displayed at the top of the app.

When a specific time frame is selected, the time that DND will be automatically turned off is also displayed in the banner.
Clicking the DND banner will open a pop-up where you can manually Turn off DND.
