Soundproofing internal French doors / doorway

[Jcuk89]

Hi,
First post in this forum, hopefully you can give me some ideas

I've just moved into a flat which previous had a living room going into a dining room, with internal French doors between.

This layout has remained but now wish to use the dining room part as a bedroom. The problem is i need to make sure these doors and doorway are soundproof, to limit disturbance between the rooms. (Bedroom backing straight onto a living room is not ideal).

The flat is rented so only semi-permanent solutions will be possible.

Does anyone have any ideas?
First thing I'll do is seal the gap underneath and around the doors. Then I was thinking of building almost like a partition that I could place in front of the doors, and maybe a big TV cabinet in front of it also. If so would need ideas for what material to use.

Pictures attached! Really appreciate any ideas.

Thanks!
What did you do with your panel doors in the end, I see you mentioned adding boards to either side of them, did it make a difference?

Well, so far I've plasterboarded the back of one of them, added wood to the bottom of it, and put double flanged draughtproofing top, bottom, and sides - It does make a very big difference, particularly to treble, but the doorway is still the place where sound is travelling. the wall insulation seems to have worked well.
I've not yet hung the second door, but if and when I do, I'll post here on the difference. I'll probably line the panels with cork mats, and again put double flange draught proofing all round.
(I was hoping to put rockwool bats on the back of the second door, but I've realised I don't have the clearance to open both doors fully if hung on the same side - I'd need to have widened the opening for the second door more than I have.)
