**[Problem/Question]**  
Hey there! How I can get a channel when I am not a member of this channel?  
I try to use

```auto
const channel = await sb.groupChannel.getChannel(CHANNEL_URL);

```

and searching queries but if I understood correctly they return channels where I am a member.  
My logic is I click on a button and I should be automatically entered (invited) to a specific channel, but before it, I need to check whether this channel is created or not. Could you help me, please?

Hello @NikShein,

A [`PublicGroupChannelListQuery`](https://docs.sendbird.com/docs/chat/v4/javascript/ref/classes/_sendbird_chat_groupChannel.PublicGroupChannelListQuery.html) instance provides several types of search filters such as `ChannelNameContainsFilter` and `ChannelUrlsFilter` . You can use these filters to search for specific public group channels.

To retrive both channels where the current user is and isn’t a member, set [membershipFilter](https://docs.sendbird.com/docs/chat/v4/javascript/ref/classes/_sendbird_chat_groupChannel.PublicGroupChannelListQuery.html#membershipFilter) to `ALL`

**Sample Code:**

```auto
const params = {
  includeEmpty: true,
  channelNameContainsFilter: 'Sendbird',
  membershipFilter: MembershipFilter.ALL
};
const query = sb.groupChannel.createPublicGroupChannelListQuery(params);
const channels = await query.next();

```
