For the accelerator to work:
1. The transaction must not have unconfirmed parent. I will also add this to OP.
2. The size must not be more than 500 bytes. Your transaction is 490 bytes
3. The fee should not be less than 10 bytes (around 19 bytes for native segwit). Your transaction is 20.245 sat/byte, which is 40.162 sat/vbyte
You transaction has 3 inputs and 1 output. If it is just 1 input or 1 output more, it would have been greater than 500 bytes. But luckily not greater.
The transaction can be accelerated.
Ones I submit it, I will let you know.
But the mempool is 41 sat/vbyte right now. Your transaction may likely be confirmed soon without using the accelerator.
Edit:
I have just checked the transaction again, as mempool dropped to 40 sat/byte just now as F2Pool mined the block ane your transaction is included. It is now confirmed without any accelerator. The fee used is enough.
