is the
autotrigger = truesupposed to show the autocomplete menu while we are editing the buffer?I've set it up with it, but when writing in a ts file for example nothing shows up, however pressing
<c-x><c-o>does show the autocomplete menuor do we have to do more configuration to have it working? thanks!
