Within Teamwork Projects, you can integrate your site with SharePoint and connect different group drives to your projects.
Click your profile icon in the top right of your site, and select Settings from the dropdown menu:
In the settings area, go to the Integrations tab where you will see an option for Microsoft SharePoint:
Once you click connect, you will be prompted to sign in to your Microsoft account and grant access.
Note: You will need administrator privileges in your Microsoft 365/Azure account in order to grant permission for the integration.
At project level, you will then be able to choose which SharePoint group drive to link to, as well as permission levels.
