Table Filter for Repeater Json Column

Hi guys.

I am having problems with the data saved by a repeater.
As the documentation says, I created a json column for the repeater and casted it to array in the model. Now I'm trying to create a filter on that column, but the

where

where

and

whereJsonContains

whereJsonContains

whereJsonContains

whereJsonContains Eloquent methods don't seem to work.
I've also tried with raw SQL but it doesn't find any record.

Here's the content of the column:

"[
  {
    \"visibility_type\":\"Section Home Page\",
    \"visibility_time\":27,
    \"visibility_price\":233.84
  },
  {
    \"visibility_type\":\"Newsletter\",
    \"visibility_time\":21,
    \"visibility_price\":200.3
   }
]"

"[
  {
    \"visibility_type\":\"Section Home Page\",
    \"visibility_time\":27,
    \"visibility_price\":233.84
  },
  {
    \"visibility_type\":\"Newsletter\",
    \"visibility_time\":21,
    \"visibility_price\":200.3
   }
]"

"[
  {
    \"visibility_type\":\"Section Home Page\",
    \"visibility_time\":27,
    \"visibility_price\":233.84
  },
  {
    \"visibility_type\":\"Newsletter\",
    \"visibility_time\":21,
    \"visibility_price\":200.3
   }
]"

"[
  {
    \"visibility_type\":\"Section Home Page\",
    \"visibility_time\":27,
    \"visibility_price\":233.84
  },
  {
    \"visibility_type\":\"Newsletter\",
    \"visibility_time\":21,
    \"visibility_price\":200.3
   }
]"

Am I doing something wrong? Thank you very much for your help and sorry for the stupid question.
