"filter for value" do not support json type

i create a test table, with attributes:

 `LogAttributes` Json CODEC(ZSTD(1)),

query result:

SELECT LogAttributes
FROM otel_logs_1

Query id: 1c5e0da4-d7cc-42eb-a202-cfd52835e2ca

   ┌─LogAttributes───────────────────────────────────────────────────────────────────────────────┐
1. │ {"host":{"name":"CDJ471X7RQ.local"},"service":{"name":"otelzap-example","version":"1.0.0"}} │
   └─────────────────────────────────────────────────────────────────────────────────────────────┘

datasource plugin:

after click filter for value,it seems use this to query, which cause a problem:

labels['service'] = {"name":"otelzap-example","version":"1.0.0"}

i want the fields with json to be look like:

host.name
service.name
service.version
