Add config.ui.meta_image

[MarkEdmondson1234]

This lets you set the meta_image that appears when sharing your Chainlit app, by default it is https://chainlit-cloud.s3.eu-west-3.amazonaws.com/logo/chainlit_banner.png but by adding to your config your own banner you can use your own.

e.g. within .chainlit/config.toml

[UI]
# Name of the app and chatbot.
name = "Your app name"

# the metadata image that appears when sharing links
meta_image = "https://chainlit-cloud.s3.eu-west-3.amazonaws.com/logo/chainlit_banner.png"

Thanks for your contribution ✨

Could you add a this image setting in a new config.ui.meta category in the configuration?

@tpatel I have updated the config as requested

Thanks for the update @MarkEdmondson1234, sorry I wasn't clear on all the things that needs to be updated. Here are some example from another PR:

• You would need to create a python class for the meta object, and add it into the UISettings class, like in this PR: https://github.com/Chainlit/chainlit/pull/787/files#diff-e76edd7e411b9e044dbc1f307015efc5d8e83f7b254af919786191f86dfc7c74R192-R199
• You would also need to update the frontend types to make sure they match the backend types, like in this PR: https://github.com/Chainlit/chainlit/pull/787/files#diff-e8a4293b0716fc7dcef3122181e5d41b58a52c46d779d352953bd0d41db43261R24-R29

Closing as the discussion has stopped, we can still reopen the PR in the future
