Generally this is normal: most SSDs (especially NVMe M.2 / PCIe SSDs) usually work at (and tolerate) higher temperatures better. 50-60 Celsius is not surprising (even in idle, when there is no read/write activity) on such SSDs.

Some models provide warning/critical temperature values recommended by the manufacturer, if this is available, the Information page may display such values.

If you prefer to avoid possible overheat alert(s) or notifications, I'd recommend to open the Temperature page of this SSD and in the upper right corner, you can configure custom warning/alert thresholds by the Set custom temperature thresholds option, so until that, the temperature will shown as "green" for this SSD.
You may even have custom alerts for any devices to prevent too frequent alerts.

Note: on the Overview page, you can also double click on the Health value (and bar) to configure custom health thresholds too for any hard disk drive or SSD. Even all disk drive(s) (hard disks or SSDs) can have different, custom health thresholds and custom temperature thresholds too and alert(s) will be triggered only when these custom thresholds reached.
