I want to make a custom module which will have a time schedule model for video meeting with some selected user . Now I want to extend a class Discuss with some major function from Discuss module like Start A Meeting, Invite to group chat and I want to call those function from my custom module. Which will redirect to Discuss module and will automatic trigger Start Meeting and will automatic Invite Selected user. Is this trully possible? and If possible how can extend Class from 'odoo-15.0/addons/mail/static/src/models/discuss/discuss.js' and How can I call those function?
