Is your feature request related to a problem? Please describe.
The framework runs after a sandbox refresh if we setup the dedicated class during refresh process.
Some users may need to run the masking outside of a sandbox refresh process, they must be able to run it manually

Describe the solution you'd like
A button on the SObjectMask record to run the masking on this object.
User should be able to select between a full run (with all the SObjectMask records or just the recordId)

Describe alternatives you've considered
Run the batch from execute anonymous window.
