Missing hyphenation info Please in stall the hyphenation package for locale 'hi'

I use this LibreOffice

CPU threads: 4; OS: Linux 5.4; UI render: default; VCL: gtk3;
Locale: en-US (en_US.UTF-8); UI-Language: en-US

For the first time this message appears: Missing hyphenation info Please install the hyphenation package for locale ‘hi’
I mainly use this writer in Thai.
Could someone tell me what should I do? or just leave it there?

Do you save as .odt (native format)?
