How to force Windows 11 to reuse the former Recovery Partition?

Before migrating from Windows 10 to Windows 11 I had decrypted my BitLocker-encrypted C:-partition - just to be on the safe side if anything goes wrong during the migration. Now, after the successful migration to Windows 11 I wanted to re-encrypt that partition.

When I started BitLocker it explained that it would first need to create a recovery partition. When I clicked OK it declared it would now first shrink my C:-drive to create space for that partition and then create a new recovery environment on it. However, I already do have a recovery partition at the end of my current system drive (at least it is labeled as Recovery Partition, its size is 1000MB/1GB).

Why does Windows 11 try create me yet another recovery partiation and does not reuse that existing one? I don't want end up having two recovery partitions one of which is useless.

Would I first have to delete that existing recovery partition, then add it to the (i.e. grow the existing) C:-drive partition such that this process can then shrink it again in order to recreate a new recovery partition? Is there no shortcut to force this process to simply re-use the existing recovery partition?
