As a slack guest user I can not update the channels topic, what if I create a bot and use https://api.slack.com/methods/channels.setTopic ? will it be possible to update the topic or will it take my guest user for this and return error?

The rights of a Slack app are defined by

  • the requested scopes at installation (e.g. channels.write, which you need to change the channel topic).

  • the rights of the installing user which are inherited (e.g. admin rights to delete messages)

So if you have a conversational bot that can be instructed to change the channel topic a guest user could use it and it would work.

Note that this will not work with slash commands though, since guest users can not use slash commands. (as described here)

As a guest user, you're unable to install applications, so you would require a regular user to install said app, and then the app would use their user token to update the topic.
