discord.customActivity emoji type

[tchavei]

I'm trying to set a custom emoji on defining a customActivity like:

emoji_current = '😬'
await self.change_presence(status=discord.Status.idle, activity=discord.CustomActivity(name='some custom activity', emoji=emoji_current))

This works perfectly.

However, when trying to use a custom emoji, it fails.

So far I tried:
→ emoji object (fails stating emoji must be type str or partialEmoji)
→ emoji as str name:id, <name:id> and <:name:id> → all fail silently i.e. no error but no emoji is added
→ emoji as dict (I was getting desperate) → same error as #1 (obvious)

What am I doing wrong?

tl;dr

unicode emoji work, custom don't. They do work if injected directly into the api with another lib but would like to avoid that

Thank you

def convert(self, ctx, argument):
        match = re.match(r'<(a?):([a-zA-Z0-9\_]+):([0-9]+)>$', argument)

        if match:
            emoji_animated = bool(match.group(1))
            emoji_name = match.group(2)
            emoji_id = int(match.group(3))

            return discord.PartialEmoji.with_state(ctx.bot._connection, animated=emoji_animated, name=emoji_name,
                                                   id=emoji_id)

        raise BadArgument('Couldn\'t convert "{}" to PartialEmoji.'.format(argument))

I've never used PartialEmoji, but this converter (used in typehints usually) essentially just converts an emoji string into a discord.PartialEmoji object.

You can use this snippet to return such an object

def get_partial_emoji(ctx, emoji_string):
        match = re.match(r'<(a?):([a-zA-Z0-9\_]+):([0-9]+)>$', emoji_string)

        if match:
            emoji_animated = bool(match.group(1))
            emoji_name = match.group(2)
            emoji_id = int(match.group(3))

            return discord.PartialEmoji(name=emoji_name, id=emoji_id, animated=emoji_animated)

Edit: Fixed the snippet after Dolfies's comment

PartialEmoji.with_state is internal, just do PartialEmoji(name=emoji_name, id=emoji_id, animated=emoji_animated)
