If you already own the microphones and just want to record for the choir's use as a reference of what they did ok, but I wouldn't do that if you want to publish it. You do have the option of plugging in external microphones. But even there the choice will be limited because, as far as I know, you don't have phantom power on the connection.

These microphones are clip-on microphones for direct speech at a distance of 10-15 cm. Room recordings are not possible or should not be made with them. This requires microphones with a cardioid characteristic, preferably stereo microphones with an MS recording or XY recording.

there are better mics for this

The mics are not particularly good for high-quality sound recordings. They are intended more for speakers.

As a part-time music producer and based on my experience with the Miks in video projects, I would say that you can probably make quite decent recordings. However, I would probably place them 1.5 - 2 metres apart so that you have a wider stereo image. Ultimately, the room will determine how satisfactory it will sound. But I would want to test it on site.
