Updates a managed memory store's description and metadata.

API scopes: agent-kit

## Path parameters

- `name` (string, required, ID, Immutable)
  Resource name in the form `memory-stores/{managed_memory_store_id}`.

## Query parameters

- `update_mask` (string, required)
  Only `description` and `metadata` may be updated. Selecting `metadata` replaces the entire map.

## Request body

The managed memory store to update. `name` is taken from the URL.
- `display_name` (string, ^[a-z0-9]([a-z0-9-]*[a-z0-9])?$, optional, Deprecated, Immutable)

   `name` as the resource identifier.
  Constraints: `[ 3 .. 56 ] characters`
- `description` (string, optional)
  Human-readable description of the memory store.
