Need help to address a Linkedin Strategy Growth - Multiple languages posts

Context

During the past year, I've seen incredible growth from agencies and/or startup through linkedin in my home country (france).

I want to replicate this basic strategy which is the following :

• start to add people who have the most chances to engage with my posts
• post consistently one to two times a day
• follow external people of my network who liked or commented my posts
• sleep and repeat

Nothing fancy, but I've seen very often that time works like magic on this.

Here's my problem

How do you deal with posts in two different languages (in my situation english and french) ?

If I post a lot in French, I might build a strong audience but only in France. Most successful "linkedin entrepreneurs" I see always post with the same language.

Network effects are strong in my native language but I also want to tackle the english speaking market.

Except that creating two linkedin accounts is forbidden and that you can get ban, the literature on the subject is pretty poor.

Does anyone grow two audiences with two different languages on the same account or with two accounts ?
