      One way to program a WSON8 chip without desoldering is to use a WSON pogo adpter, and they are not very reliable.

      https://www.aliexpress.com/item/1005001830846980.html Please note that if you decide to buy one of these you must get one thats the correct size for the chip. The two most common sizes are 8x6mm and 6x5mm ,measure the size of the chip with a ruler or vernier calipers.
      ...

      I recommend hot air station to unsolder the chip, then WSON8 do DIP8 adapter:
