liberation strategy connection

[MaximoSanchez]

Hello everyone.
I have the following question:
in my company we want to implement the approval and request of orders through the “my inbox” application of fiori.
currently we have an approval strategy implemented in sap gui, then the question is: if we implement the my inbox application, could an approval strategy using sap gui be used together with the my inbox application of fiori?
i.e. if the purchase order has to go through 3 approvers, could 2 approvers use sap gui and 1 approver use my inbox?
I have not found any official sap information on this and it would help me to have it, also obviously if you answer me to this question.
Thank you very much and if you have any doubt please reply me to clarify my question,

Sorry I am not in approval strategies and think this is procurement specific. Are with approval strategy workitems created? If yes, you could approve these also in My Inbox. If you do not have experiences in course BIT602 MyInbox is discussed https://training.sap.com/course/bit602-sap-workflow--overview-basics-strategy-and-extensibility-clas... On which system you operate?
