Power Fx is a DataSourceInfo function that can be used in building a Canvas app using the 'Accounts' table of Dataverse datasource. This function allows you to show a button only if the logged in user has 'Delete' permission on the 'Accounts' table. The DataSourceInfo function provides information about a particular column of a data source as well as permission details, such as Create, Read, Write and Delete permissions.
For example, to get the 'Display Name' and 'Max Length' of a column, the DataSourceInfo function can be used as follows:
"MaxLength of 'name' column is - "& DataSourceInfo(Accounts, DataSourceInfo.MaxLength)
