Is there a way in SPFx to create custom action in “PersonalAction” group

XML element method is working for classic pages, for modern pages it is not working.

Using SPFx list view command set I can create ECB menu for list item level I am unable to find anything for personal actions which will work in modern UI as well.

For Sharepoint Online I tried Site/Web.UserCustomActions.add().

For SharePoint 2019 on premise I tried:

<CustomAction       Id="MyID"       Title="MyTitle"       Description="MyDesc"       Location="Microsoft.SharePoint.StandardMenu"       GroupId="PersonalActions"       ImageUrl="cust/image/path"   >     <UrlAction Url="cust url"/>   </CustomAction> 

None of the above worked for modern UI.
