How to represent custom token in header in Swagger UI(swagger.json) in nodejs

Question

I am creating a Restful server in ExpressJs. I have integrated swagger-jsdoc. Following is the related files. Below(header.png) is how I expect my header to look like in swagger UI. But, while I open my swagger UI (http://localhost:3000/api-docs/), I am not able to see Token tags (token and Authentication) in the header.

swagger.json

app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument));
app.use('/api/v1', apiRoutes);

You are missing the security tag. You can define it either globally just below the securityDefinitions tag or one for each API endpoint.
