Ai agent web searches tool

[TEJAS]

Hi Community ,
My requirement is if the user ask for query in the now assist panel it should get me the answer 
so i am using the tool web searches .
so i referred to this link for web searches
https://www.youtube.com/watch?v=LZSVkHfTc1k&t=542s 

but in this the provider they are using is Gemini AI answer but in my instance for me it is showing default as Azure OpenAI answer

so i created Gemini AI answer in oneExtend Definition Configs and made Gemini AI answer to default 

But now also in the provider it is showing as Azure OpenAI answer
Can any say what mistake i have done.

Thanks in advance
