API Access to LCA App Functions for EPD attachment

As a third-party developer,
I want to access specific functions of the LCA app via API,
so that I can call the function in my app, such as adding EPDs that utilize the LCA app's hash function.

Description:

The LCA app offers a hash function that is essential for adding EPDs. To facilitate integration with other applications, it's important to make this function accessible. This will allow developers to call the LCA app's hash function, ensuring consistency when attaching EPDs.
