Can we do it with `ClassTag` ?
You can't with a class tag, as it represents the erased type as known to the JVM. You could use a TypeTag
to reify the full type, but that depends on full scala reflection, which has its own downsides
(not thread safe, basically pulls in the compiler,...)

Given a dictionary, transform it to a string. Then byte encode that string. Then base64 encode it and since this will go
on a url, use the urlsafe version. Then decode the byte string so that it can be else where.
data = base64.urlsafe_b64encode(json.dumps({'a': 123}).encode()).decode()
# And the decode is just as simple...
data = json.loads(base64.urlsafe_b64decode(query_param.encode()).decode())
# Byte encode the string, base64 decode that, then byte decode, finally transform it to a dictionary
