/**
 * @module SecretListHeaderTab
 * SecretListHeaderTab component passes in properties that are used to check capabilities and either display or not display the component.
 * Use case was first for the Database Secret Engine, but should be used in future iterations as we don't generally want to show things the user does not
 * have access to
 *
 *
 * @example
 * ```js
 * <SecretListHeaderTab @displayName='Database' @id='database-2' @path='roles' @label='Roles' @tab='roles'/>
 * ```
 * @param {string} [displayName] - set on options-for-backend this sets a conditional to see if capabilities are being checked
 * @param {string} [id] - if fetching capabilities used for making the query url.  It is the name the user has assigned to the instance of the engine.
 * @param {string} [path] - set on options-for-backend this tells us the specifics of the URL the query should hit.
 * @param {string} label - The name displayed on the tab.   Set on the options-for-backend.
 * @param {string} [tab] - The name of the tab.  Set on the options-for-backend.
 *
