Applying Filter to finschia-sdk Module in Custom CosmosMsg Using SubMsg

[da1suk8]

Here is a possibility that the finschia-sdk module can be invoked within a Custom CosmosMsg via SubMsg. Given this, it seems necessary to apply a filter to prevent the use of the finschia-sdk module.

The task is to check if there is a need to apply a filter and, if necessary, proceed with its implementation.
