Failed to add multiple AzureAISearchTools in ToolSet

• Package Name: azure-ai-agents
• Package Version: 1.1.0b1
• Operating System: Ubuntu 22.04
• Python Version: 3.10.12

Describe the bug
I have several Azure AI Search indexes, each responsible for a different set of knowledge. I would like to convert these AI Search indexes into tools, so that my AI Agent can use the appropriate tool (i.e., index) depending on the specific task.

I tried adding these tools using ToolSet, but I encountered the following error:

Traceback (most recent call last):
  File "/workspace/Azure_Agent/61_Agent_ToolSet.py", line 98, in <module>
    toolset.add(ai_search_tool2)
  File "/usr/local/lib/python3.10/dist-packages/azure/ai/agents/models/_patch.py", line 1206, in add
    raise ValueError("Tool of type {type(tool).__name__} already exists in the ToolSet.")
ValueError: Tool of type {type(tool).__name__} already exists in the ToolSet.

Here is my code:

ai_search_tool1 = AzureAISearchTool(
    index_connection_id="xxx",
    index_name="index1",
    query_type=AzureAISearchQueryType.VECTOR_SEMANTIC_HYBRID,
    top_k=3,
    filter=""
)
ai_search_tool2 = AzureAISearchTool(
    index_connection_id="xxx",
    index_name="index2",
    query_type=AzureAISearchQueryType.VECTOR_SEMANTIC_HYBRID,
    top_k=3,
    filter=""
)

toolset = ToolSet()
toolset.add(ai_search_tool1)
toolset.add(ai_search_tool2)

with agents_client:
    agent = agents_client.create_agent(
        model="gpt-4o",
        name="agent-sdk-kk-with-toolset",
        instructions="You are a helpful agent. To answer user question, you can use tools to retrieve information from diff AI Search Tools",
        toolset=toolset,
    )

Could you please help me understand how to properly configure this setup, or let me know if there are any limitations I should be aware of?

Thank you in advance for your assistance.
