Add Bearer token

i have a issue of add Add Bearer token in webview. i added the token in rest api end points like this

'securityDefinitions' => [
                'securitySchemes' => [
                    'bearerAuth' => [
                        'type' => 'http',
                        'scheme' => 'bearer',
                        'bearerFormat' => 'JWT',
                        'value' => 'ThisIsASampleToken123'
                    ],
                ]
            ]
