Try It Out Not Working With Multiple Security Schemes

My OpenApi spec has multiple security schemes (see the example below). When viewing my API documentation, I can only see the first scheme. How do I select which one should be used in my ReadMe documentation?

securitySchemes:  
	apigee_security:  
		type: apiKey  
		name: x-orgid  
		in: header  
	bearer:  
    type: apiKey  
    name: Authorization  
    in: header
