Hi @keylama ,
Do you want to update the current user's info (e.g. Office Phone, streetAddress) within canvas app?
If you want to update the current user's info (e.g. Office Phone, streetAddress) within canvas app using Office365Users connector, I afraid that there is no way to achieve your needs.
Firstly, the Office 365 Users connector is a action data source, which you could not bind it to a Edit form, and use the Edit form to update the user profile info. You could only execute the Office365Users actions within behavior property of control, e.g. OnSelect property of a button.
In addition, the Office365Users.UpdateMyProfile() function in canvas app could only update the following properties:

you could not use the Office365Users.UpdateMyProfile() function to update the officePhone, streetAddress property.
As an alternative solution, I think custom connector could achieve your needs. You could consider create a custom connector based on Microsoft Graph REST API, then specify the "Update user" action within your custom connector. After that, in your app, create a connection to this custom connector, use the custom connector action to update user Profile.

On your custom connector, you should define the following action path:
