The shortcode requires the widget ID, but no need to guess, the plugin generates the code for you. To override the widget title for a widget you can use the “title” parameter: 
 [widget id=”text-1″ title=”New title”] 
You can also hide the widget title entirely if desired: 
 [widget id=”text-1″ title=”0″]
Additional Parameters:
<ul>
<li>container_tag: the HTML tag to use for the widget container, default: <code>div</code></li>
<li>container_class: CSS classname added to the widget container, default: <code>widget %2$s</code> (Note: uses sprintf for variable substitution)</li>
<li>container_id: HTML ID attribute for the widget container, default: <code>%1$s</code> (Note: uses sprintf for variable substitution)</li>
<li>title_tag: HTML tag to use for the widget title wrapper, default: <code>h2</code></li>
<li>title_class: CSS classname for the widget title wrapper, default: <code>widgettitle</code></li>
</ul>

Widget Shortcode

I had tried another plugin to use a widget in the gutenberg block editor on a page, however that plugin had some issues so was not ideal.

Widget shortcode enabled me to add my widget by copying the generated shortcode to the shortcode block in the block editor, resulting in the widget being displayed perfectly on the page. 

Works perfectly with the block editor

Adds [widget] shortcode which enables you to output widgets anywhere you like.

InfoTuts

User can easily create a contact form and integrate it any where in website. It gives shortcode [sw-contact-form] and a widget to add any where in the website. 
It allows user to select the way they want to receive user entries in three ways as given below:
1) Contact form entries would be sent to users email. 
2) Contact form entries can be saved in database and user can view it in dashboard. 
3) It can do both i.e. send contact form entries to users email and also save in database so that user can view it.
Contact form entries when saved in database, user can view email ID’s and use those as leads so this plugin empowers user to generate more lead from contact forms.
SW contact form also adds Google’s No Captcha recaptcha to prevent spamming. User can enable this feature.
The plugin also allows to custom style the contact form by adding Custom CSS.

SW Contact Form
