Modifying an existing bookmark through slash command is not optimal

[jfrerich]

Once a bookmark exists, modifying the bookmark with the /bookmarks add command overwrites the bookmark and does not provide an update option.

slash command

1) In the following scenario, the labels are added, but not the title

repro:

• /bookmarks add <postId>
• /bookmarks add <postId> Add a title --labels=<newlabel1>,<newlabel2>

2) In the following scenario, label2 is dropped and user is not informed. Here we should automatically add the existing labels when --labels used, or show the user the differences in the bookmarks before and after in an ephemeral message, showing them the differences

repro:

• /bookmarks add <postId>
• /bookmarks add <postId> Add a title --labels=<newlabel1>,<newlabel2>
• /bookmarks add <postId> Add a title --labels=<newlabel1>

possible suggestion

Once the UI is merged, add to the ephemeral message of a /bookmarks add command letting the user know the UI exists and is easier to modify bookmarks
