I have made a quick action in lightning web component and want ot make that compponent available for quick action. I havenot found any guide or documentation regarding this. Can you please suggest on how to make the lwc available for quick action.
This is not supported yet. You can have a look to what's supported and what's not here.
What you can do is wrap your Lightning web component in an Aura component:
<aura:component implements="force:lightningQuickAction"> <c:myLwc></c:myLwc> <aura:component>
If you need to send events like
force:closeQuickAction, you'll have to first send an event to the enclosing Aura component, so that it could fire this action. More on this here.
You should be able to pass record id from lightning component to lightning web component and build your functionality there. Check this blog for detailed information https://theashcode.com/salesforce-lightning-web-components-with-quick-actions/
