When writing a front-end and back-end application, my group elements become lists when they are passed between the front-end and back-end. How can I restore their data types?

I think you can try to serialize the elements first before passing them, and then deserialize after receiving.

Serialize:

bytesString = group.serialize(element)

Deserialize:

element = group.deserialize(bytesString)
