See Table 6 and Table 46.

The die paddle (exposed pad) is connected to VSS through high ohmic (non-conductive) silicon attach and must be electrically isolated. It is good
engineering practice to solder the exposed pad to an electrically isolated PCB copper pad as shown in Figure 46 for better heat transfer but it is not
required as the RTC doesn’t consume much power. In no case should traces be run under the package-exposed pad.

See Table 6 and Table 48.
