Zigbee Tuja door sensors TS0203 latest firmware update

Hello! I’m using TS0203 Tuja door sensors a lot, with firmware shown as 0x00000046. How can I ensure that this is the latest version and (if not) how can I get updates? I have made the experience that HA might not showing updates for devices (for example Sonoff TRVZB) until you provide a correct z2m_remote_index in the zha → zigpy_config → ota - section in the configuration.yaml.

But I couldn’t find any hint where to get the updates for the TS0203.
