Call in ST

Description

The CheckProductFeatureLicense function can be used at runtime to determine whether the active license contains a specific key/flag. The result can then be used, for example, to control subsequent program execution. The key is actually represented by a key-value pair. Support for working with the “value” component is planned for the future.
