Is there a way pass "login_hint" for OAuthPrompt

[NWH-SAmin5]

Is your feature request related to a problem? Please describe.
Some of the functionality which can be automated through a bot instead of web experience, becomes more than needed steps, which can be reduced with optional parameter like login_hint

Describe the solution you'd like
Provide ability to pass optional query string parameter in OAuthPromptSettings. This will be able to pass username in the login url reducing steps and improving end user experience.

AI generated Example Implementation
Here is an example of how you can set up an OAuthPrompt with the login_hint parameter in the Bot Framework:

const { OAuthPrompt } = require('botbuilder-dialogs');

const oAuthPromptSettings = {
    connectionName: process.env.CONNECTION_NAME || 'Myconnection',
    text: 'Please sign in',
    title: 'Sign in',
    timeout: 300000,
    // Additional parameters for OAuth
    additionalOAuthParameters: {
        login_hint: 'user@privilegedaccount.com'
    }
};

this.dialogs.add(new OAuthPrompt('OAuthPrompt', oAuthPromptSettings));
