With the help of the Stream Delete Store Variable Action it is possible to delete an existing store variable in the Stream Variable Store by specifying the name (key) of the variable.
This is only possible if the variable is not protected.
To remove the protection of a store variable, one need to do this manually by accessing it via the Stream Variable Store.
Keep in mind to use only the variable key "test1234".
Using the wildcard "{store.variable.test1234}" would lead to an issue due to syntax error.
