You'll want to unlock the museum that allows you to try this, as it's where you may donate your specimens in case you do not want to promote, gift, or hold them. Curator Blathers is answerable for the museum, and you may be able to donate gadgets directly to him. You'll need to free up the museum as you figure in the direction of getting your first shovel.
From day one you could start the method of unlocking the museum. On your first day at the island, after the academic section, Tom Nook will accept five extraordinary fish or insects. He is gathering those within the hopes that the native plant life and fauna at the island could be sufficient to trap Blathers to transport to the island. It works, of course--after handing within the 5th specimen, Blathers will ring Tom Nook and agree to arrive at the island the next day.
Tom Nook will then give you a camping tent to put down for Blathers and the future website online of the museum. This might be the spot in which the museum will subsequently be built, so make certain to pick someplace you want, because it ACNH Bells could be some time until you free up the capacity to transport homes round.
