Questions about Sony Charging Case

Are there any new charging cases for the Sony WF-1000XM5? As I've lost mine, I'm looking for a new one. There is one for the WF-1000XM4 here: https://www.digitec.ch/de/s1/product/sony-charging-case-wf-1000xm4-kopfhoerer-ersatzteile-22955523?supplier=406802&utm_source=google&utm_medium=cpc&utm_campaign=PROD_CH_PMAX_CSS_Cluster_8&campaignid=20496494580&adgroupid=&adid=&dgCidg=EAIaIQobChMIvPfHjcO8hwMV5JiDBx08XyzLEAQYByABEgJ1J_D_BwE&gad_source=1&gbraid=0AAAAADnW3waiN_d2TLaOV_mk1vYsM7mTc&gclid=EAIaIQobChMIvPfHjcO8hwMV5JiDBx08XyzLEAQYByABEgJ1J_D_BwE&gclsrc=aw.ds But this is not compatible with the new generation

@SonyEuropeBV Where can I get in touch with you, do you have an e-mail address or telephone number?

I'm looking for a right bud, can they also be bought separately? My right one only lasts 15 minutes and then it's empty after almost 3 years, which is a real shame for such an expensive product (bought at launch for 270).

This product page was suggested to me by a search engine after I searched for a charging case for the product "WF-1000XM5". Have I been misled? Or should compatibility be assumed? Can it be returned if not compatible?

Can I use the case for the sony linkbuds s?

Will this charging case work with the SONY WF-1000XM4?
