Is it possible to somehow transfer the “value” to another function?

class Application(disnake.ui.Modal):
    def __init__(self):
        components = [
            disnake.ui.TextInput(
                label = "Your nickname",
                placeholder = "nickname",
                custom_id="Nick"
            )
        ]
        super().__init__(title="Application", components=components)
    async def callback(self, inter: disnake.ModalInteraction):
        embed = disnake.Embed(title="Your registration data")
        for key, value in inter.text_values.items():
            embed.add_field(name=key.capitalize(),
                            value=value[:1024],
                            inline=False
                            )
        await inter.send("You have successfully submitted your application, please wait for a response", ephemeral=True)
        #print(f"{selgcomponents.placeholder}")
        print(Application.components(disnake.ui.TextInput(value)))
        liv = d1()
        await bot.get_channel(channel id).send(f"Nickname: {value}", view=liv)

I’m new to Python so I don’t know how to do this
