tabularray (CTAN: Package tabularray <https://ctan.org/pkg/tabularray>)
provides longtblr environment that is called as

---
\begin{longtblr}[various-table-options]{column and row specifications}

\end{longtblr}
---

Adding something like the following to orgmode tables makes them export
nicely as longtblr

---
#+ATTR_LATEX: :environment longtblr
#+ATTR_LATEX: :align
width=0.8\textwidth,colspec={lX[2,r]X[3,r]X[r,bg=gray9]}
#+ATTR_LATEX: :booktabs t
---

Everything seems to work very well with orgmode except that I cannot figure
out how to pass [various table options] from orgmode. These table options
include, most importantly, table notes.

I normally use threeparttable for table notes, but longtblr does not seem
to work with threeparttable and has its own syntax for table notes.

Any advice on how to pass [table-options] to longtblr environment?
