Don't worry about it. In practice, the officer only looks at the PR card, ID and passports for 99% of applicants during the interview, during which the originals are technically required, but they will stay in your briefcase.
And the oath is a formality in term of documents. Mine was a super quick ID check before they took my PR card. I suppose it's a simple ID verif on camera now before they ask you to cut the card during the oath zoom call.
