Attributes for HTMX extensions

[pintariching]

I'm trying to use the HTMX SSE extension, but it seems it's not implemented yet. Here's what I get:

maud! {
    div hx_ext="sse" sse_connect="/status" sse_swap="status-update" {
        ...
    }
}

error[E0599]: no function or associated item named `sse_connect` found for struct `hypertext::prelude::hypertext_elements::div` in the current scope
  --> crates/scada-server/src/axum_ui/status_view.rs:26:26
   |
25 | /     maud! {
26 | |         div hx_ext="sse" sse_connect="/status" sse_swap="status-update" {
   | |                         -^^^^^^^^^^^ function or associated item not found in `hypertext::prelude::hypertext_elements::div`
