Libreoffice version suppot

hi, im trying to build my image with a combination of alpine, nodejs and libreoffice in order to do some office file handling inside my container.
ive come to the conclusion that in my usage i need libreoffice in version 6.4.7.
for some reason when i try to add it to my image i can only get version “LibreOffice 6.4.4.2”.

im just trying to understand if a solution is available so if not i will make the correct changes:
Dockerfile code:

FROM node:14.16.0-alpine3.10

RUN apk update && apk add bash

# Install libreoffice
RUN apk update
RUN apk add libreoffice

thanks!
