Hi @YaswanthGummadivelli: I don't think you have options to add buttons. Can you please look into this for details.

Please also see this regarding limitations.

Also pleas see this from QNA

Can we have a button on Cosmos React? For example I wanted to have a filter fields and a search button. and on click of that button some action needs to be performed?

You don't configure buttons. You have data patterns and vew definitions. Based upon that you will get the search functionality.

You can post your questions on Ask the expert discussion here too.

Thanks.
