One remark: you should not have User or Tag references in a generic import pop-up.
If we import more entities in the future, this part will be a pain to maintain.

-> Use sub-component to display dedicated form controls for User and Tag according the entity type.
-> Type the dialog data Inject(MAT_DIALOG_DATA) data like in GeoMapDialogComponent and provide enums for data like 'entity'.
-> Increase also the button size which is cropped in french ;-).

That's it :-).
