Mutli select UI component

[kklas]

We’d like to support the ability for users to create multiple accounts / public keys in our Snap (https://suisnap.com), but the problem is, when the user is connecting to a web3 app, how does it tell it which accounts should this app be able to access? Allowing all accounts is a privacy issue. So this is not possible because there’s no way to create a multi select UI within the Snap where the user could select one or more accounts that the app would be able to access. I propose mutli select custom UI component support is added.
