Let users to Create only in SharePoint List, but can not Edit

I'm building a sharepoint list (SPO, input form is customized by PowerApps) for an approval form, with PowerAutomate.

The flow is running well, but the problem is users could Edit/Delete the record in the approval request list.

I'm wondering how to make the "Edit" and "Delete" button of the list disable but only "Create"?

Or any work around?
