UTXO method 404 not found when using own mempool instance with romanz/electrs

[cryptoteun]

I'm running my own mempool.space instance, it's using romanz/electrs.

When I do a 'scan blockchain' in the extension, I get a lot over 404 not found on the utxo endpoint.
Some research ended in this issue with the mempool.space project:
mempool/mempool#4644

Based on this comment of @softsimon, the error is because of the missing endpoint in the electrs implementation:
mempool/mempool#4644 (comment)

Is it possible to get the needed info via another way?

Currently only the mempool space api is supported.
